JEFF The Brotherhood -- Sat, 1:30pm JEFF the Brotherhood have been touring relentlessly for years, making a reputation for themselves as one of the best rock shows around. The Nashville brothers duo -- who also run their label, Infinity Cat, out of their hometown -- have been playing their garage rock jams since 2001, when they were still in high school. Before landing on mega-fests like Lolla, they spent years playing sweaty makeshift illegal show spots and basement ragers and self-booked tours with DIY purists like Screaming Females. Now on their seventh studio album -- and first for a major label -- they're touring this summer with Hypnotic Nights, produced by the Black Keys' Dan Auerbach. It's their poppiest yet, but still full of head-banging garage rock: good-time anthems that are at once heavy and hooky.
