Radiohead frontman Thom Yorke announced today (Feb. 25) that his side project, now officially named Atoms for Peace, will play an eight-date U.S. tour leading up to its performance at the Coachella Music & Arts Festival. The band's trek will kick off at New York's Roseland Ballroom on April 5-6 and hit the Santa Barbara Bowl in California on April 17, the day before its headlining gig at the Indio, Calif. fest. 

Previously billed as ????, Atoms for Peace -- named after a song on Yorke's 2006 solo album "The Eraser" -- consists of Flea of the Red Hot Chili Peppers, Beck drummer Joey Waronker, producer Nigel Godrich, and Forro in the Dark percussionist Mauro Refosco. Yorke first unveiled the group last October at Los Angeles' Orpheum Theater.

In a Thursday morning post on Radiohead's Dead Air Space blog, Yorke wrote, "Ok so in April the other band.. that i got together to do the eraser and other stuff u know .. Mauro, Flea, Me, Joey and Nigel is going back out to do some shows in the US.. ending with playing with Coachella. we had too much fun to just leave it there..."
