"I Froze Up" (2002)
The sparse, haunting "I Froze Up" originally premiered during one of Radiohead's off-kilter webcasts in 2002, where Thom Yorke performed the song solo on a Fender Rhodes piano. This heavily bootlegged, low-bitrated version of "I Froze Up" was the only evidence the song ever existed ... until 2010, when Yorke revived the track at a February solo concert in Cambridge, England. Two months later, "I Froze Up" popped up again, this time at an Atoms for Peace concert in Chicago, but that would be the last time Yorke revisited the somber cut.
"Morning Mr. Magpie," another track that Yorke debuted during that December 2002 webcast, was also all but forgotten before its inclusion on Radiohead's The King of Limbs, which gives fans hope that "I Froze Up" could also one day be released from the vaults. D.K.
