You’ll forgive us if we don’t automatically take Death Grips at their word. Late last night, the group released niggas on the moon, the first half of their forthcoming double album the powers that b., as a free download. In characteristic Death Grips fashion, this whole thing was a surprise, and not everyone believed them when they claimed that Björk appears on every track. (Many news outlets used the word “allegedly” to describe those Björk appearances.) But yeah, no, that’s her on there. Here’s what Björk says about the experience:

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” ! i have been lucky enough to hang and exchange music loves w/ them and witness them grow !! epic : onwards !!
