Radiohead frontman, Thom Yorke, teamed up with producers Burial and Four Tet on two tracks, which have now been leaked on the internet.
The tracks were originally played on Rinse FM on 15/3/11, the songs have since been put on YouTube.
Entitled Mirror and Ego, both feature everything you'd expect from the artists involved. Bags of ambience, slow-groove loops, and some undecipherable Thom Yorke lyrics.
The collaborations will be released on 12-inch from Four Tet's label.
