Thom Yorke’s once-mysterious side project got a name yesterday: Atoms for Peace (sensibly, it’s a Dwight Eisenhower reference). Now it also has some tunes: Yorke played a solo benefit show for the U.K. Green Party at an awesome-sounding venue called the Cambridge Corn Exchange, and Radiohead fan site At Ease has graciously provided nice, clean YouTube clips of the three brand-new songs he played. (They're all embedded below.) He played acoustic guitar on the ones called “Mouse Dog Bird” (our favorite, if you’re an extremely busy person and only have time for one previously unreleased Thom Yorke song a day) and “Give Up the Ghost” (which, by the way, is also the name of our favorite Boston hard-core band), but he tickled the ivories for “The Daily Mail.” There’s also some charming stage banter, if you’re into that kind of thing. While you’re listening, just imagine how much better these will sound once Flea drops the slap bass on 'em.
