Underground guitar hero Ty Segall hit the stage in a striped T-shirt with a ripped left shoulder, showing off some red skin that really needed to be anointed with SPF 30. Heedless of the danger of skin cancer, however, he led his three bandmates through one great song after another. (He has a lot to choose from, having released approximately three kazillion solo albums and collaborations in the last five years.) The songs came in two flavors: fast psychedelic freakouts and even faster garage-rock stompers. If Segall ends up burning and peeling, it was totally worth it.
