@newnewpollution: TURNS OUT THE GUITAR ON DEATH GRIPS' "BIRDS" IS ROBERT FUCKING PATTINSON.

ETA: Pitchfork posted more details about how they recorded that:
It's been confirmed that this is true. Zach Hill recorded Pattinson's guitar with his iPhone and the band sampled the recording on the track.
