Avicii

On 24 January 2020, another posthumous single by Avicii was released: "Forever Yours", which is a collaboration with Kygo and Sandro Cavazza. The song was previously performed by Avicii during his final tour in 2016, starting with Ultra Music Festival. Kygo and Sandro Cavazza performed the song together live at the Avicii Tribute Concert back in December 2019. On 15 February, Tiësto premiered three unreleased Avicii singles on the latest episode of his radio show Tiësto's Club Life: A fifth collaboration with Aloe Blacc called "I Wanna Be Free", a fifth collaboration with Sandro Cavazza called "We Burn" and a fifth collaboration with Wyclef Jean called "Now That We Found Love".

In April 2019, it was announced that the album Tim, which Avicii was working on before his death, would be released on 6 June 2019, with the first single, "SOS", released on 10 April. All proceeds from the sale of the album go towards the Tim Bergling Foundation. Also in April, it was announced an official biography of Avicii, written by Måns Mosesson, would be released in 2020, the proceeds also going to the Tim Bergling Foundation.

A second single from the album, titled "Tough Love", was released on 9 May 2019. The music video for "Tough Love" was released on YouTube 14 May 2019.

"Heaven" which was released on 6 June 2019 was the last single to be released from the album. The track was co-written by Coldplay's lead singer Chris Martin. Chris spoke about the collaboration on his socials citing that he co wrote the song with Avicii back in 2014 which Tim completed in 2016. The music video, called a "tribute video", which used old clips of Avicii, was released on 24 June 2019. On 28 June, Billboard cited "Heaven" as one of the best dance songs of the first half of 2019.

On 8 September 2019, on what would have been Avicii's 30th birthday, some unreleased songs, never meant to be heard by the public, were leaked on the internet. Two of them feature demo vocals from Tim himself, "Promises of Tears" and an early version of "No Pleasing A Woman". The latter was also sung by Green Day frontman Billie Joe Armstrong. In December, two singles were released on the networks, "Alive" with Wyclef Jean and "Lethal Drug" with Chris Martin of Coldplay. "Fades Away" featuring MishCatt was also released in December after being performed in Stockholm at the Avicii Tribute Concert for Mental Health.

On 30 April 2019, the Mounted Royal Guards and the Life Guards' Dragoon Music Corps of the Swedish Army paid tribute to Avicii during a ceremony at Stockholm Palace, where brass renditions of his songs "Without You", "Hey Brother", and "Wake Me Up" were played.

The 2019 Edition of the music festival Tomorrowland included a tribute in the decoration of the Main stage of the festival.

In September 2019, it was announced that a tribute concert would be held in Stockholm on 5 December 2019 in memory of Avicii. The concert saw David Guetta, Kygo, Dimitri Vegas & Like Mike, Nicky Romero, and Laidback Luke headlining, along with a number of vocalists that Tim had worked with playing alongside a 30-piece orchestra, fulfilling one of Avicii's dreams for his music in a live setting. All profits went to the Tim Bergling Foundation. Following the start of ticket sales, the concert sold out in 30 minutes.

On 26 March 2019, Bergling's family launched a mental illness and suicide prevention foundation, named after the late DJ, the Tim Bergling Foundation. The foundation works internationally and aims to educate people and businesses on the issues surrounding suicide and mental health. The foundation also works to tackle climate change, manage business development, and conserve endangered species. People in the music industry are already claiming Avicii's death has raised awareness of mental health in the industry.

Avicii also influenced a number of mainstream artists outside electronic music. Nile Rodgers said that in terms of melody writing, Avicii was "maybe one of the best, if not the best I’ve ever worked with." Mike Einziger of Incubus said "Some of the work we did together is some of the music I’m most proud of in my whole life." Dan Reynolds of Imagine Dragons said "working with [Avicii] was one of my favorite collaborative moments." Charlie Puth said that Avicii was "The man who really opened my eyes as to what my productions could one day sound like." Eric Clapton, who never publicly worked with Avicii, said he was "Inspired by Avicii", and dedicated a song off his Christmas album, Happy Xmas, to him.

On 21 November 2019, Billboard named Avicii's 2011 hit "Levels" as one of the one hundred songs which defined the 2010s, whereas his 2013 hit "Wake Me Up" came 13th (and was the highest charting EDM song) on the Official Charts Company's chart of the decade.

Bergling retired from touring in 2016 due to health problems, having suffered from stress and poor mental health for several years. On 20 April 2018, he died by suicide in Muscat, Oman. He was buried on 8 June at Hedvig Eleonora Church in his hometown. His posthumous third album titled Tim was released in 2019.

On 10 February 2018, Bergling released "Ghost", a collaboration with Swedish singer-songwriter Daniel Adams-Ray, who was credited as HUMAN. The song, which was leaked on the internet in 2014/2015 under the title "(I'm Still) In Love With Your Ghost", marks the second collaboration with the 2 Swedes following "Somewhere In Stockholm" from Bergling's album "Stories".

Following Bergling's death that April, news outlets reported that at the time of his death, he had over 200 unreleased songs, some finished and others still in development. It was further stated that he had produced some of the best songs in his career before his passing. In August 2018, producer Carl Falk, who co-produced some of the songs on Bergling's Stories album in 2015 and Avici (01) in 2017, stated that he's putting the finishing touches on the Chris Martin collaboration "Heaven" (originally written during the Stories sessions) and that it might be posthumously released in a few months along with the third album.

Bergling died on 20 April 2018 near Muscat at the age of 28. No cause of death was immediately given. On 21 April, the Omani police stated that there was "no criminal suspicion" or evidence of foul play in Bergling's death. On 26 April, his family released an open letter stating:

On 1 May, TMZ reported that the cause of death was a suicide due to self-inflicted injuries with a broken wine bottle, with Bergling eventually dying of blood loss. On 22 May, Bergling's family announced plans for a private funeral with "the people who were closest to him". A funeral service was held on 8 June at the Skogskyrkogården cemetery in Stockholm. He was buried at Hedvig Eleonora Church in June 2018.

On 20 May 2018, American DJ duo The Chainsmokers and American singer-songwriter Halsey paid tribute to Bergling at the 2018 Billboard Music Awards before presenting the winner of the Top Hot 100 Song. The Chainsmokers’ Drew Taggart said, "His passing was a great loss for the music world and for us. He was an artist who inspired so many in so many ways, and simply put, he meant so much to us and everyone in the EDM community." Halsey then delivered an emotional discussion about mental health and emphasized the need for people to love and support each other.

During the performance, Keys made a verbal tribute to Avicii.

On 16 November 2018, Bergling's family organised a public memorial service at the Hedvig Eleonora Church in Stockholm. The service saw a huge turn-out, with hundreds of fans filling the church to mourn and pay their respects. The service featured an orchestral choir which played music linking to events in Bergling's life and ended with a version of his 2013 number one hit "Wake Me Up". One fan described it as a "very moving" service and "a great tribute to Bergling".

In June 2017, British singer Rita Ora debuted a semi-acoustic version of "Lonely Together" at a private event at Annabel's in London. "Lonely Together" was later the second single from Avīci (01).

Bergling uploaded teasers of each track from the EP online upon release.

On 10 August 2017, Bergling released the six-track EP Avīci (01). Bergling said of the release: "I'm really excited to be back with music once again. It has been a long time since I released anything and a long time since I was this excited over new music! My focus on this first EP of the album was to get a mix of new and old songs: some that fans have been asking about and waiting for mixed with brand new songs that they haven't heard before!"

In an interview with Pete Tong on BBC Radio 1, Bergling stated that the EP is one of three parts of his third studio album.

Avicii inspired many artists in the EDM genre, many of whom paid tribute to him after his death. Norwegian DJ Kygo cited Avicii as "[his] biggest inspiration and the reason why [he] started making electronic music." In addition, artists like Alan Walker and DubVision described him as an "icon" in EDM. Other artists such as Diplo, Sebastian Ingrosso, Felix Jaehn, and Martin Garrix, the last of whom collaborated with Avicii on his 2015 single "Waiting for Love", have also cited him as a source of inspiration, with the songs "Levels" and "Seek Bromance" being specifically mentioned as points of inspiration.

On 21 March 2014, Bergling released a remixed edition of his album True titled True: Avicii By Avicii containing remixes by himself of all the tracks, excluding "Heart Upon My Sleeve" for unknown reasons.

His manager, Ash Pournouri, admitted that he knew of Bergling's health problems but refused to label them mental health problems. Furthermore, his management team only became aware of his painkiller addiction in November 2014. They staged two interventions for him, neither of which were successful. Pournouri rescheduled many shows in order for Bergling to recover in Stockholm. Having discovered his client's alcohol issues earlier, Pournouri set out to forbid his promoters from offering him alcohol, clearing out his minibar and focusing on his recovery. Problems worsened, however, when there were no crew to "keep tabs" on Bergling during his recuperation.

On the same day, Bergling released "I Could Be the One" with Nicky Romero. After first being debuted at his shows almost a year earlier, the track finally got released via Bergling's record label LEVELS.

In March 2013, Bergling announced and premiered many new tracks from his new album True, which would later be set to be released in September, during his Main Stage set at Ultra Music Festival in Miami. The new tracks were experimental in nature. For example, Bergling brought out a stomping band to play through the new bluegrass-tinged song "Wake Me Up". Many of these new songs received mixed critical reviews after the concert.

On 11 April 2013, Bergling released his new album promo mix on SoundCloud. It contained some songs from True and some of his non-album singles. It also contained some of his ID's such as "Black and Blue" and "Enough is Enough (Don't Give Up On Us)".

Our beloved Tim was a seeker, a fragile artistic soul searching for answers to existential questions. An over-achieving perfectionist who travelled and worked hard at a pace that led to extreme stress. When he stopped touring, he wanted to find a balance in life to be able to be happy and to do what he loved most – music. He really struggled with thoughts about Meaning, Life, Happiness. He could now not go on any longer. He wanted to find peace. Tim was not made for the business machine he found himself in; he was a sensitive guy who loved his fans but shunned the spotlight. Tim, you will forever be loved and sadly missed. The person you were and your music will keep your memory alive. We love you, The Family

On the day of his death, The Washington Post wrote an article citing Avicii as a pioneer artist in the attempt to bridge the gap between country and electronic music, crediting his 2013 hits "Wake Me Up" and "Hey Brother" as a good example of this movement. Avicii is also credited for influencing other attempts at continuing this genre crossover, including songs such as Zedd's "The Middle" and Hailee Steinfeld's "Let Me Go".

In 2012, his collaboration track "Sunshine" with David Guetta was nominated for a Grammy award under the category for Best Dance Recording. His track "Fade into Darkness" was sampled by Leona Lewis on her single "Collide". The sampling was not accredited and led to controversy as Bergling attempted to block the single's release. The matter was resolved out of court with representatives stating "that Leona Lewis and Avicii will work together on the forthcoming single of Collide".

On 23 March 2012, Bergling's unsigned single "Last Dance" was previewed on Pete Tong's show on BBC Radio 1. The song was later released on 27 August 2012.

The track features vocals from Eric Turner. A radio edit of the track, titled "Dancing in My Head" (Tom Hangs Mix) was released on 14 August 2012 on iTunes, and a remix EP was later released on 30 October 2012 featuring remixes from Charlie Bernardo and Michael Woods. On 26 September 2012, Bergling made history as the first DJ to headline the world-famous Radio City Music Hall in New York City. He performed two sold-out shows on 26 and 27 September. He was supported by Matt Goldman and Cazzette at the two shows. At his Radio City Music Hall shows, he played a preview of his new track with Mike Posner titled "Stay with You".

On 29 December 2012, Bergling premiered many new songs at Lights All Night, Dallas Convention Center, some of which made it on to his first album, True. These unreleased songs included "I'll Be Gone" and "Let It Go". The instrumental of "Let It Go" was mixed with the a cappella of "Addicted to You" to become "Addicted to You (Avicii by Avicii)".

In January 2012, Bergling was hospitalized for 11 days in New York City with acute pancreatitis caused by excessive alcohol use. In 2014, Bergling underwent surgery and had both his appendix and gallbladder removed. In 2016, Bergling's health deteriorated, and he retired from performing live. In the 2017 documentary Avicii: True Stories, directed by his close and longtime collaborator Levan Tsikurishvili, Bergling spoke about his physical and mental health struggles. The documentary depicts the pressure from his management to continue performing live in spite of his objections.

At the age of 16, Bergling began posting his remixes on electronic music forums, which led to his first record deal. He rose to prominence in 2011 with his single "Levels". His debut studio album, True (2013), blended electronic music with elements of multiple genres and received generally positive reviews. It peaked in the top ten in more than fifteen countries and topped international dance charts; the lead single, "Wake Me Up", topped most music markets in Europe and reached number four in the United States.

In 2011, Bergling released "Levels", which launched him into the mainstream. "Levels" reached the top ten in Austria, Belgium, Bosnia, Croatia, Denmark, Finland, Germany, Greece, Ireland, Italy, the Netherlands, Slovenia and the United Kingdom, whilst topping the charts in Hungary, Norway and Sweden.

After achieving widespread commercial success, Bergling began working with his manager and executive producer Ash Pournouri to start House for Hunger in 2011, a charity dedicated to alleviating global hunger. The pair wanted to showcase the giving spirit fostered by the house music community. Bergling explained, "You have to give something back. I am so fortunate to be in the position where I can actually do that. I feel lucky every day when I wake up and am able to do what I love and make a living." In addition to donating $1 million to Feeding America, a charity founded by John van Hengel, House for Hunger has helped fund the efforts of The Feed Foundation, started by Laura Bush, allowing it to distribute over 2 million school meals throughout Africa. He also supported campaigns against human trafficking and gang violence when he directed the videos for his tracks "For a Better Day" and "Pure Grinding".

Tim Bergling was born in Stockholm on 8 September 1989, the son of Klas Bergling and actress Anki Lidén. He started mixing in his bedroom at the age of eight. He had three siblings: David Bergling, Linda Sterner, and Anton Körberg. Inspired by his brother, who was also a DJ, he began making music at the age of 16. In May 2007, Bergling signed on with the Dejfitts Plays label. He was a member of the Laidback Luke Forums, where he refined his craft and, at times, demonstrated his distinct deep house style. By 2009 to 2010, Bergling was a prolific producer and was releasing music incredibly quickly. His remixes during this period were "Sound of Now", "Muja", "Ryu" and "Even". Bergling explained that the name Avicii means "the lowest level of Buddhist hell" and he chose the moniker because his real name was already used upon creating his Myspace page. Then, in 2010, Bergling released the hit song "Seek Bromance", which reached the top 20 in several countries, including Belgium, France, the Netherlands, United Kingdom, and Sweden. He also remixed Nadia Ali's classic single "Rapture" for her album Queen of Clubs Trilogy: Onyx Edition. In October 2010, Bergling signed with the European A&R team with EMI Music Publishing.
