You would be forgiven for being slightly cynical as to whether these are actually Thom Yorke or not, especially considering the recent hoax the band pulled, posting a song which apparently was a unreleased track fron The Bends era. It actually turned out to not be Radiohead at all. Ever the puppeteers of their own PR.
That aside, these two tracks have been confirmed as the real Thome Yorke. They were made for Rag and Bone fashion collection in New York. No word on how they featured or whether they were part of a longer mix. Regardless, Thom seems to be embracing the "post dubstep" movement with arms spread wide and willing.
Not sure anyone can argue with the results.
