Record number two from Teri Gender Bender and Le Butcherettes is a bit of a departure from their debut; the garage fumes have cleared to reveal blinking, oscillating keyboards on a handful of tracks, and sharp-edged, post-punk guitars on another. Songs like “New York,” “Bang” and “Dress Off” still reek of late-night, Yeah Yeah Yeahs-flavored aggression, but tracks like “The Leibniz Language” are brilliantly original and uncategorizable: there’s a dash of cabaret on this song, as it moves from a languid pace to artful and urgent punk-derived drama. “Help me! Put me back together,” Teresa Suarez pleads before the song shifts yet again into another form. Songs like “The Actress That Ate Rousseau” and  “Mr. Tolstoi” are not merely shallow nods to intellectual expression, but rather evidence of the former philosophy student’s knack for clever wordplay and brawny musical constructs that take post-punk to another place. Omar Rodriquez Lopez of At the Drive-In and the Mars Volta plays bass and produced Sin Sin Sin, which is a surprisingly more complex affair than one might have expected.
