Bear witness to one of Seattle's most interesting bands. They bill themselves as "digital folklore," and Terror/Cactus definitely make music that embodies the paradoxical tension between modernity and tradition. With roots in Argentina, multi-instrumentalist Martín Selasco and his mask-wearing bandmates ingeniously mix cumbia, exploratory electronic music, and surf rock on their debut LP, Impulsos. These danceable hybrids sound like futuristic party music to which you drink cocktails made with ingredients you've never heard of. by Dave Segal
