If you’re one of the many people shocked and hooked by Le Butcherettes’ ferocious live performances (mega-babe singer Teri Gender Bender wears a blood-stained apron, “eats” pig heads, and does backward flips into the audience) but weren’t sure about the band’s music amid so much noise and theatrics, here’s the whole package. Produced by Omar Rodríguez López (the Mars Volta, who also played bass on all tracks), Sin Sin Sin is the full-length debut by a band that started in Guadalajara as a female duo but is exploding into fuller shape as a co-ed artsy garage punk trio. The fully bilingual Teri (born in Denver as Teresa Suárez) is a limited player (guitar and keyboards) but a fierce strummer and a powerful, versatile vocalist who sings virtually every track as a different character. There’s unusual variety here for what is ultimately a garage rock record, including straight-ahead punk, Bikini Kill aggression, and avant-garde polka-ish Cossack beats sung over with a fake Russian accent. Get this now, and check her out live June 3 at AT&T Center with Deftones and The Dillinger Escape Plan.
