Elusive UK dubstep demigod Burial just unveiled his latest work set to see the light of day, a collaborative 12″ with trip-hop veterans Massive Attack. The two-song record, “Four Walls” b/w “Paradise Circus,” is limited to only 1000 copies, and is available to pre-order now from The Vinyl Factory. While you wait for your record to arrive, you can catch the premiere of the whole thing tonight on Zane Lowe’s Radio 1 show, and also stream the 12-minute a-side cut below.
