We’re still awaiting Radiohead’s follow-up to 2011’s The King of Limbs, but at least Thom Yorke’s staying busy. Really, really, really, busy, apparently. Yorke’s friend and artist Stanley Donwood, who created all but one of the band’s album covers (Pablo Honey), has a retrospective art exhibit in Sydney, “The Panic Office,” running through June 6. It’s backed by a Yorke-created composition called “Subterranea” that’s 432 hours and, according to People, is different from minute to minute. Nothing better than checking out some art accompanied with “an eerie mix of ambient textures and experimental sounds.” If you want to catch Yorke’s piece, though, scurry off to Australia: There are no plans to release it outside of this setting.
