The rap-punks continue their unpredictable streak.

Death Grips are no stranger to surprise releases, having shared No Love Deep Web for free — much to the chagrin of their label.

The band is back with niggas on the moon: eight free tracks that feature unspecified contributions by Björk. This is the first installment of a double album titled the powers that b that is due out later this year on Harvest/Third Worlds Records; the second disc is titled jenny death.

Stream/download the album below or via Mega. “peace & love,” the band wishes on Facebook. “have a sad cum bb.”

Update: Björk has taken to Facebook to comment on the project: “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 !!”
