John Bush

Bush appeared on the 2019 Ellefson album Sleeping Giants, supplying lead vocals for the track "If You Were God."

Bush provided vocals for the track "Bound by Silence" from Metal Allegiance's 2018 album Volume II - Power Drunk Majesty.

In September 2015, Bush caused some minor controversy after he went public concerning royalty issues with Anthrax, explaining: "they've had a lot of — a lot — of accounting and management issues that were affecting me personally. Dan Spitz has an issue with the band [...] he feels like he hasn't been paid by the band. And the dude made seven records with Anthrax. And the dude should be paid on those records that he made with the band. [...] It's, like, I'm out there signing Anthrax records I made. I just wanna be paid for the records [that were] made and sold. And it gives me pride in those records. And then when you don't [get paid], you become very bitter about it, and it's not cool." He did reveal however that the band had a new accounting company and that "they seem to be on the up and up now"

Bush provided vocals for Konami's 2013 action game "Metal Gear Rising: Reveangeance". He is featured on the tracks "Return to Ashes" and "The Hot Wind Blowing".

In April 2011, German instrumental rock band Long Distance Calling released a self-titled full-length album, which features John Bush performing vocals for the track "Middleville". "Middleville" is the only track with vocals on that album.

In December 2011 Metallica performed a 30th anniversary show with several guests, including Bush. joined Metallica onstage to perform "The Four Horsemen", a song from Kill 'Em All where he took the lead vocal as Hetfield wanted him to do almost three decades prior. After the performance, drummer Lars Ulrich took the mic to say "It could have been a whole different story," then added in amazement at Bush's performance: "Wow!"

In August 2009, after Anthrax parted ways with their replacement singer Dan Nelson, Bush rejoined his former bandmates in Anthrax for a live performance on August 1, 2009, at the Sonisphere Festival in Knebworth, England. Following this performance, there were many calls for him to return full-time. John Bush also performed with Anthrax at the Loud Park '09 Festival in Japan on October 17, 2009, followed by five concerts on the Soundwave tour in Australia in February 2010.

On December 14, 2009, it was announced that the "Big Four" Thrash bands would play in Poland and Czech Republic during the following year, among several other shows during the Sonisphere festival. It was expected that Anthrax would continue with Bush, but the other members ultimately chose to reunite with Joey Belladonna, as Bush was not up for recommitting to the group full-time. The band has since toured and recorded again with Joey Belladonna.

In early 2005, Anthrax issued a press release stating that the band's Among the Living lineup was reuniting. Anthrax stated that Bush had not been fired, but with Joey Belladonna's return and talk of a new album in the works, it was unclear if Bush would record with them again. However, Joey Belladonna's exit from Anthrax in January 2007 fueled reports that Bush would return. However, Anthrax chose to recruit a new vocalist, Dan Nelson. In June 2007, John Bush stated during an interview that he was not bitter about the split with Anthrax, revealing that they had asked him to take part in the reunion tour, which would have seen him and Belladonna splitting vocal duties, but that he turned it down because "it just wasn't right" for him. He was later approached again by the band to re-join following Belladonna's exit, which he again turned down, explaining: "I couldn't go back and say, 'Here I am...' It would be like coming in with my tail between my legs, and that's not right for me. I just couldn't do that. It just didn't feel right to do that. It was about soul, your gut. How does that feel? Does it feel right? Good enough. Sold. Answer."

In 1999, whilst Bush was a member of Anthrax, Bush got together with Armored Saint bassist Joey Vera. Together they decided to bring back the Symbol of Salvation lineup for an Armored Saint reunion. The resultant album Revelation was released in 2000 and a short tour followed. The following year, Armored Saint released a collection of demos, live tracks and other rarities in the two disc package Nod to the Old School. They have since released two more studio albums, La Raza in 2010, and Win Hands Down in 2015.

Following the 1992 dissolution of Armored Saint, Bush received a call from Scott Ian of Anthrax, who offered Bush the chance to fill the spot left behind by singer Joey Belladonna, who had been fired from the band. Bush accepted and joined the band, adding alternative rock sensibilities. Anthrax recorded Sound of White Noise, Stomp 442, & Volume 8: The Threat Is Real with Bush in the 90s before entering a temporary hiatus during 1999. Despite Bush's reunion with Armored Saint during that same year, Bush remained a member of Anthrax. Returning to the band, Bush recorded vocals for his fourth album with the band, the critically acclaimed We've Come for You All in 2003. The successful WCFYA tour was documented with a live album/DVD titled Music of Mass Destruction. In 2004, Anthrax released The Greater of Two Evils, a re-recording of several of the band's more popular songs from the pre-Bush era with the then-current lineup.

In 1990, original Armored Saint guitarist Dave Prichard died of leukemia during the recording of Symbol of Salvation. Jeff Duncan replaced Prichard and the band finished the recording of Symbol of Salvation, going out on tour afterwards. Despite rave reviews from the metal press, the band decided that they just didn't want to continue without Prichard, and amicably disbanded.

In 1984 John had a cameo appearance in the Huey Lewis and the News video "The Heart of Rock & Roll" at the 1:38 mark (exiting from the limo).

Since their formation in 1982, Armored Saint has released six full-length albums, one EP, a live album, a greatest hits compilation and two DVDs, all with John Bush on vocals.

In the early 1980s, Bush was invited by Metallica to join them as lead singer. Even after the release of Kill 'Em All, Metallica vocalist James Hetfield felt unsure about his singing abilities. Hetfield wanted to concentrate on his guitar and personally asked John Bush to join Metallica. Bush was the only vocalist that the band considered as a potential frontman. He turned down the offer as he wanted to stay with Armored Saint. Bush states that part of his loyalty to Armored Saint came from the band being made up of his closest childhood friends.

They started at Wilson High School, Los Angeles (auditorium) in 1979.
