Proto-grunge rock band formed in 1983, after the break-up of the hardcore band Deep Wound, of which Lou Barlow and J Mascis were members.
Following the 2005 reissue of the first three Dinosaur Jr. albums (Dinosaur, You're Living All Over Me and Bug), the original line-up of J Mascis, Lou Barlow and Murph, reformed to tour that material. They also returned to the studio to record and release new material.
