Death Grips last night (June 8) dropped another surprise album for free, and when the controversial duo claimed Bjork was featured on each track for this one, it was welcomed with the appropriate dose of skepticism. But this afternoon, Bjork herself confirmed that she is in fact on Niggas on the Moon.

“I am proud to announce my vocals landed on the new death grips album ! i adore death grips and i am thrilled to be their ‘found object’ !” she wrote on her Facebook page.

The avant-rap release is apparently the first part of a double album the powers that b., and you can stream the whole first half below.
