DJ /rupture is back with a musical response to Joshua Oppenheimer’s acclaimed documentary The Act of Killing.

Oppenheimer and DJ /rupture (aka Jace Clayton) have collaborated before, so Stage Boundary Songs feels particularly deeply realized. Clayton has clearly spent time with the polarizing film, which deals with the aftermath of atrocities committed by a number of sanctioned death squad leaders in the 1960s, and his response is chilling and revealing.

Taking a handful of folk, rock and pop songs from the era surrounding Indonesia’s coup, Clayton blends these tracks with poems from local poet Wiji Thukul (who is described as “an icon of the country’s leftist democracy movement”), audio snippets from the film itself and more recognizable cuts, such as Holly Herndon’s excellent ‘Chorus’ and The Durutti Column’s ‘Opera’.

Oppenheimer and co-director Anonymous made this statement about Stage Boundary Songs:

“We live, sleep, dream, and die atop mass graves. Terror and lies prevent us from mourning the dead below us. We no longer remember that we are afraid – it is easier to forget. In this stifling silence, thieves and extortionists help themselves to the spoils like buzzards, reinventing themselves as respectable politicians and entrepreneurs. Yet for those who have the courage to listen, there are cries of resistance, voices of clarity calling for an end to fear, and longing for solidarity. In Stage Boundary Songs, we hear some of the most eloquent of these voices. We are humbled that our film helped inspire this effort.”

All of Clayton’s mixes are essential listening, and this surprising blend is no different – you can stream it in full now over at Pitchfork.

Update: The mixtape is now available to stream/download.
