Best known as the remote frontman of the influential indie trio Dinosaur Jr., J Mascis has also been an occasional producer and film composer. Born December 10, 1965 in Amherst, MA, he first emerged as a member of the hardcore unit Deep Wound, founding Dinosaur in 1984. Over the course of acclaimed LPs like 1987's You're Living All Over Me and 1988's Bug, the group emerged among the most highly regarded in alternative rock, with Mascis' creaky, Neil Young-like vocals and monolithic guitar leads becoming primary influences on the burgeoning grunge movement. The group temporarily disbanded in 1989, largely to allow the legendarily non-communicative singer the opportunity to dismiss bassist Lou Barlow, who went on to form Sebadoh; in the meantime, Mascis sat in on drums with a series of bands, among them the Velvet Monkeys and GobbleHoof, even producing the latter's eponymous 1990 LP. Upon re-forming Dinosaur Jr. in 1991, he scored Allison Anders' independent film Gas Food Lodging a year later, making a cameo appearance in the picture itself; he and Anders became regular collaborators in the years to follow, most notably on her feature Grace of My Heart. Mascis also produced records for pals including fIREHOSE (Mr. Machinery Operator) and Tad (Inhaler), and in 1996 issued his solo debut Martin + Me.
