Dinosaur Jr

Dinosaur Jr. is an American rock band formed in Amherst, Massachusetts, in 1984. The band was founded by J Mascis, Lou Barlow, and Murph (drums). After three albums on independent labels, the band earned a reputation as one of the formative influences on American alternative rock. Creative tension led to Mascis firing Barlow, who later formed Sebadoh and Folk Implosion. His replacement, Mike Johnson, came aboard for three major-label albums. Murph eventually quit, with Mascis taking over drums on the band's albums before the group disbanded in 1997. The original lineup reformed in 2005, releasing five albums thereafter.
