J Mascis

The manager for Deep Wound was Gerard Cosloy, who then went on to found Homestead Records. Homestead released Dinosaur Jr.'s first record. Mascis says that the reason why Dinosaur Jr.'s sound is not fully formed on that record is that they were more or less automatically signed to Homestead. Megan Jasper, vice president at Sub Pop Records characterises this period as "J had some anger, like any punk rock kid. Usually, though, when a young person is angry, they tend to be really loud. And J wasn’t. He was only loud when he played music".

Mascis joined Unknown Instructors on their fourth album, replacing Joe Baiza as guitarist. The album, Unwilling to Explain, was released in 2019.

In April 2014 he played with reunited Nirvana on a secret gig after the Rock and Roll Hall of Fame inductions. He sang the songs School, Pennyroyal Tea and Drain You. In August 2014 he released the solo album Tied to a Star on Sub Pop and toured in support of it.

Mascis plays guitar and sings backing vocals on the song "Feed" by the now inactive post grunge band Japanese Voyeurs. "Feed" can be found on the band's only album to date, "yolk", released independently July 2012.

Mascis released a mostly acoustic album in March 2011 titled Several Shades of Why on Sub Pop Records. He was joined in the studio by several guest musicians, including Kurt Vile, Ben Bridwell and Sophie Trudeau. Mascis toured North America with Vile as support act to promote the album. In 2013 Richard Ayoade cast J Mascis in a small role, a caretaker, in his film The Double. Mascis's electric guitar work is featured on the 2014 Strand of Oaks album Heal.

December 2011 saw the release of the Squier by Fender J Mascis Jazzmaster. This features a basswood body, C-shaped maple neck, rosewood fingerboard with 9.5" radius and 21 jumbo frets, two high output single-coil Jazzmaster pickups, three-position switching and dual tone circuits, gold anodized aluminum pickguard, aged white plastic parts (knobs, switch tip, pickup covers), Adjusto-Matic™ bridge with vintage-style floating tremolo tailpiece, vintage-style tuners, chrome hardware, Vintage White finish, and J Mascis signature on the back of the large '60s-style headstock. Mascis replaces the stock pickups with Kinman Guitar Electrix ThickMaster (Jazzmaster) Zero-Hum pickups. These are, however, excluded from the factory guitar.

In 2010 Mascis joined with John Petkovic and Tim Parnin of Cobra Verde and Dave Sweetapple of Witch to form Sweet Apple. The self-titled debut album was released on Tee Pee Records. Mascis plays drums, guitar, and sings on the album.

July 2007 saw the release of a signature guitar by Fender, the J Mascis Signature Jazzmaster. The instrument comes in a Purple Sparkle finish and, while otherwise visually similar to a standard Jazzmaster, features a few modifications J requested.

In 2006 Mascis returned to drumming with his newly formed heavy metal band Witch for their self-titled debut album.

In April 2005 Mascis, Barlow, and Murph reformed the band for a tour celebrating the re-release of the group's first three albums. The reunited line-up has since released four new albums: Beyond in 2007, Farm in 2009, I Bet on Sky in 2012, and Give a Glimpse of What Yer Not in 2016.

In August 2005 Mascis released J and Friends Sing and Chant For Amma, a solo album under the J Mascis and Friends banner. The album consists of devotional songs dedicated to Hindu religious leader Mata Amritanandamayi, or Ammachi, about whom he had written "Ammaring" on the first J Mascis + The Fog album More Light. The proceeds from the album are being donated to tsunami relief efforts Ammachi's organization is spearheading. In 2008 the six-track album was made available digitally on his own Baked Goods label.

In 2000 he began producing albums with his new band, J Mascis + The Fog. In 2003, the house and studio he owned burned down.

As a side project, he was the drummer in Boston doom metal group Upsidedown Cross, who released a self-titled album on Taang! Records in 1991. He wrote songs for the film Gas, Food, Lodging, in which he made a cameo appearance. In 1996, he had a small part in the movie Grace of my Heart and provided a ballad and a Beach Boys-like song for the soundtrack. In 1998, he retired the Dinosaur Jr. name.

His wife, Luisa, whom he met in New York in the mid 1990s and married in 2004, is from Berlin, Germany They reside in Amherst, Massachusetts, in a house formerly owned by Robert Thurman, a professor of religion noted for his work on Buddhism, and father of actress Uma Thurman. In September 2007 they had a baby boy named Rory. His brother-in-law is German filmmaker Philipp Virus, the director of the 2006 Dinosaur Jr. DVD Live in the Middle East. He is a devotee of Mata Amritanandamayi, a Hindu guru and author. Mascis explained that he discovered her in the mid 1990s when "I was at my lowest, as the band got bigger, I got more depressed. I was looking for anyone to help, to feel better".

Mascis was born in Amherst, Massachusetts, the son of a dentist and grew up in the same area together with his sister Patty and an older brother. His mother, Theresa (an avid golfer), died in 1985 while his father, Joseph Sr., died in 1993.

In 1982 Mascis became straight edge, part of a hardcore punk associated movement whose members avoid drug and alcohol abuse. Since then, he has mostly been a teetotaler and never used other recreational drugs.

Mascis became a music fan and drumming enthusiast at the age of 9. He later joined the jazz ensemble in school as a drummer. At 17, Mascis joined the short-lived hardcore group Deep Wound with Lou Barlow, Scott Helland, and Charlie Nakajima in the early 1980s. He went on to found Dinosaur Jr. with bassist Barlow and drummer Emmett Jefferson "Patrick" Murphy (aka "Murph") in 1984, switching to guitar in the process, and they achieved national success. His vocals have been described as "Neil Young-like" and his guitar riffs as "monolithic". Mascis dismissed Barlow from Dinosaur Jr. in 1989 and over the next eight years recorded several more Dinosaur Jr. albums, as well as the 1996 acoustic solo album Martin + Me. In 1989 Kurt Cobain suggested that Mascis join Nirvana.
