On the heels of swirling internet rumors, Thom Yorke of Radiohead has formally announced the upcoming release of the  "FeelingPulledApartbyHorses"/"The Hollow Earth" 12′' single, due only two-and-a-half weeks from now.

The first of those tracks was written around 2001 but is a "radical rework" featuring and co-written by Radiohead noisemaker/guitarist Jonny Greenwood, Yorke says in a press release. "'The Hollow Earth' is a bass menace that was born out of the 'Eraser' period but needed a little more time," he continues, referring to his July 2006 solo release. Like you, we're not sure what he means by bass (base?) either.

The vinyl release and a free download of the tracks will go up on Sept. 21 in the band's W.A.S.T.E. store while the songs will go to the rest of digital outlets "around" Oct. 6. They were produced by frequent collaborator producer Nigel Godrich.

"They are loosely under the Thom Yorke name this time, although these days its all getting kind of blurry." No kidding. Particularly with the secret/leak/not-secret one-off releases of "Harry Patch" and "These Are My Twisted Words."

Plus there's the continuing anticipation swirling about his writing a track for "Twilight Saga: New Moon," which was confirmed to us by director Chris Weitz in July. Perhaps its no coincidence that these tracks are being released around the immenent release of the "New Moon" soundtrack on Oct. 13, when all will be revealed.

Because YouTube is magical, we have an early version of "FeelingPulledApartbyHorses" from 2005. By now it could have glockenspiels and be sung in French, but that magnificent Yorke whine will likely endure.
