Indie noise rock pioneers Dinosaur Jr. have maintained their stature in the genre for decades now, and they’re not letting up. Fronted by the ever-creative J Mascis, the band vaults madly between chest-thumping, bone-crushing punk structures and more laid-back, contemplative melodies. Bring earplugs. These guys like it loud. Doors to tonight's show at the Agora open at 7.
