The ever-expanding Radiohead tour of North America continues, with precious new tracks dropped along the way. This time it's "Skirting On The Surface," or "Skirting," depending on Thom Yorke's mood, a track he's been known to play solo but that the band hadn't touched together. Playing with all of them in Dallas last night, Yorke described the multi-titled "Skirting" as "a song no one's heard yet," before launching into a Hail To The Thief-era buildup. As with "Identikit" and "Cut A Hole," the two reveals from the start of Radiohead's tour last month, fans were at the ready to record the whole thing. Check out the fanvid below.
