Well, this is quite a surprise: Radiohead's Thom Yorke, Four Tet, and dubstep enigma Burial have teamed up for a 12" on Four Tet's Text record label. The A-side is called "Ego", while the AA-side is "Mirror".

A press release notes that both tracks will air tonight, 11:00 p.m. GMT, on UK radio station Rinse FM during Four Tet's session with UK knob-twiddler Floating Points. You might remember that Burial and Four Tet have teamed up before for 2009's "Moth" / "Wolf Cub" single; you can listen to "Moth" below.
