Timothy Lockwood Armstrong (born November 25, 1965), known simply as Tim Armstrong, and earlier in his career known as Lint, is a Grammy Award-winning American musician, songwriter, artist, poet, record producer and independent record label owner. During the 1980s he and longtime bandmate Matt Freeman served in several seminal hardcore and ska punk bands in the East Bay music scene, most notably the band Operation Ivy. In 1991, he and Freeman formed the punk rock band Rancid, which is credited with the mainstream revival of punk rock in the mid-1990s and is one the most commercially successful punk bands of all time. In 1998, he, along with Brett Gurewitz, the guitarist of the band Bad Religion and owner of Epitaph Records, founded Hellcat Records. In 1999 Armstrong formed the hip hop/punk rock supergroup the Transplants. During Rancid's temporary hiatus between the albums Indestructible and Let the Dominoes Fall, he released his ska-oriented solo album, A Poet's Life in 2007. As of 2012 he has produced several albums, including Jimmy Cliff's Rebirth, and has directed a number of films.
