Radiohead Premiere "Testcast," Cover Björk

Radiohead have stepped up on the promotion of their return by jumping the gun on tonight's scheduled live webcast and doing a "testcast" last night (November 8) via their special webcast site. As always, they get weird and cryptic with the proceedings, but what begins with a Thom Yorke DJ session, unfurls into a lovely cover of Björk's "Unravel," which Pitchfork have provided an MP3 of. In addition, Jonny Greenwood and producer Nigel Godrich each try their hands at manning the decks.
