Enjoy this lo-fi rip while you can.

On Tuesday, mysterious Swedish duo The Knife will release their first new music since 2006′s Silent Shout (2010′s Planningtorock and Mt. Sims collaborations aside), and you can preview it now. The nine-minute techno epic is confounding and anxious, with ragged bits of dissonant synthesizer, colliding percussion, and Karin Dreijer Andersson’s groaning vocals.

Stream ‘Full of Fire’ below, but excuse the low-quality. The song is the first single from the group’s long-awaited new album Shaking The Habitual, due on April 8 through Brille / Mute.
