Radiohead debuted a new song while beginning their North American tour last week in support of their album 'The King of Limbs'. The track is called 'Skirting on the Surface' and has only been previously played live during frontman Thom Yorke's solo tour. The alt rock kings decided to dust off the gem for live audiences to enjoy.

'Skirting on the Surface' is indeed a Radiohead original but was never officially released for whatever reason. Yorke would add the song in his set list during 2009-2010. As reported by NME, the track is the third new song the band has revealed during this current tour, joining 'Identikit' and 'Cut A Hole'. You can watch a video of 'Skirting on the Surface' below. The footage is from their concert in Dallas, Texas.

Radiohead have announced additional North American tour dates yesterday for the months of May and June. The British rockers will also headline two sold out weekends at the Coachella Music Festival April 14 and the 21, and appear at the Bonnaroo Music & Arts Festival in Manchester, Tenn., on June 8. After that, the group will head to Europe from July through October and New Zealand and Australia in November.
