I've gotten into some heated discussions in the past few weeks over which Dinosaur Jr. lineup is better, the years with Lou Barlow or Mike Johnson? This isn't even a question I would raise. Why? Because J. Mascis is the sound. Trust me, your eyes will be glued to J. Mascis ripping and shredding the hits from You're Living All Over Me. Dinosaur Jr. play tonight and tomorrow evening at the Troubadour. Even the opening bands will be loud.
