Before Japanese rock was fashionable, before metal was respectable, Zeni Geva combined math, metal, and psychedelia with such ferocious abandon and deadly precision that they commanded a devoted following in the Chicago underground–Steve Albini collaborated with them on All Right, You Little Bastards (1995) and Jim O’Rourke recorded with founding member KK Null around that time as well. Now Null and Mitsuru Tabata are back with their first album in five years, 10,000 Years of Light (on Neurosis’s Neurot Recordings), and while their sound seems to be set in stone, they still flatten most of the competition. Some might find their single-mindedness unnerving, but to me it’s refreshing: they’ve mastered their grimy futurism, and they’re sticking to it. This bill also includes Arab on Radar (see Critic’s Choice), Behold! The Living Corpse, and a solo set by Null–for those who still believe in genuine rock ‘n’ roll wildness, this is the place to be.
