What little exposure Holy Fuck has gotten in the U.S. came during stints backing avant-rapper Beans, but at home in Toronto this dance cabal is an all-star team. You could call them a jam band, but it’d be more accurate to say they’re an electro group that uses real instruments and makes it up as they go along. The fluid lineup–as many as six dudes total–sometimes features two drummers, and everybody else has their hands full with synths, bass, guitars, samplers, tape machines, effects pedals, and even a couple noninstruments (the band imitates the sound of turntable scratching with a 35-millimeter film synchronizer). They don’t write songs, and the tracks on their recent self-titled album for Dependent were drawn from two unrehearsed live-to-tape sessions–most of the time, though, you can hardly tell. The techno thunder can get pretty seriously thumpy and clubtastic, and they do motorik Teutonic drone even better–imagine what the Juan McClean’s most stoned band practices would sound like. And despite leader Brian Borcherdt’s hippie-dipshit description of Holy Fuck’s mission–“capturing a vibe in a moment and interacting with people”–their live show is rumored to be capable of inducing ass-shaking even in non-Canadians. Arks and Rain Delay Theatre open; DJ Jarrett spins between sets. Thu 1/19, 9:30 PM, Empty Bottle, 1035 N. Western, 773-276-3600 or 866-468-3401, $8.
