When the current lineup for Radiohead front man Thom Yorke's "other band" first played last October at LA's Echoplex they didn't have an official name. People then were referring to them as "Thom Yorke and Friends" or as the "Thom Yorke and Flea side project" band. In fact, when the lineup for this year's Coachella Festival (April 16, 17, 18 in Indio CA) at which they are one of the main attractions on the closing day, was initially announced, they were simply billed under the name ????.  Consisting of Yorke, Red Hot Chili Peppers bassist Flea, producer Nigel Godrich on keyboards, and session percussionists Joey
Waronker and Mauro Refosco, the group, under Yorke's orchestration, has settled on the band name Atoms For Peace. However the Coachella website currently lists the band simply as "Thom Yorke," no doubt for easier recognition & less confusion.
