A few years ago (2012 to be exact), a remix of SBTRKT's 'Hold On' surfaced by someone calling themselves SiSi BakBak, but no one knew who that was. Today, Thom Yorke has revealed himself to be behind the remix via Consequence of Sound. It's now listed on Radiohead's online store under the 'Thom Yorke/Atoms For Peace' section, if you want to see for yourself. Stream the remix below.
