The recently reunited Dinosaur Jr. remain one of the titans of independent (and not just "indie") rock. They are as renowned for their deft guitar work and squalls of feedback as for the tensions between band members J Mascis and Lou Barlow. On Beyond, their first album since 1998 with all the original members, the animosity is gone, but the tense/slack musical dynamic remains. People say the live shows are a winning mix of gray nostalgia and renewed energy. (Neumo's, 925 E Pike St, 709-9467. 7 pm, $20, 21+.)
