With the excellent Farm, J, Murph, and Lou are back and spry as ever. And with their colossal amp and pedal rigs, they are eardrum rupturing as ever, too. Dinosaur Jr. is touring to show everybody how it’s done, yet again, last night playing the second of a sold-out two-night stand at the Troubadour. Tomorrow night they’ll rattle teeth and test the mettle of Jimmy Fallon’s sound crew, so set your TiVOs. Opening were Long Beach psychedelic punkers and CMJ faves Crystal Antlers, and photographer Andrew Youssef was on hand to snap both.
