We all know the dance floor can be a dangerous place. What with all of those flailing limbs, gyrating pelvises, and spastic movements, total chaos can and does easily ensue. Thanks to Canadian electro phenomenon MSTRKRFT — who seem to have everyone and their baby's mama getting down — club violence has taken on a whole new meaning with the murderous single "Street Justice," off their seething debut, The Looks (Last Gang, 2006). Urgent, screeching-siren guitars squeal under the thumping bass and the ominous chant "This is a killing on the dance floor," conveying the imminent threat of sonic carnage and giving the notion of "killing it" a threatening new meaning.

Made up of JFK, the bass player of now-defunct electrorock outfit Death from Above 1979, and Al-P, DFA 1979 producer and a former member of quirky electric pop combo Girlsareshort, these two have perfected a mix of raw, hormone-heightening, boogie-worthy beats with a savage rock sensibility. With a sound that nods to house legends Daft Punk but without their asexual austerity, JFK and Al-P combine electro-fueled urban grit with sultry rock 'n' roll, appealing equally to dance diehards and of-the-moment musical opportunists. Masquerading in stage attire as evil as their thumping racket, MSTRKRFT have been known to don gold spray-painted hockey masks as they man the decks, a sinister look that's more Jason Voorhees than Gallic space visitor. Liberally passing Crown Royal bottles around onstage, this sensual duo liven up their club appearances with their naughty golden dancers, who wear the signature masks and little else, making steamy remixes like "Sexy Results" that move beyond pure aural fantasy.
