Radiohead Rocks NYC With 'Limbs,' R.E.M. Nod & 'Rainbows'
Thom sings at Roseland.

Radiohead were all about unreleased tracks and rarities last night (Feb. 27) at the Miami kickoff of their first proper U.S. tour in four years.

Radiohead Rocks NYC With 'Limbs,' R.E.M. Nod & 'Rainbows'

The U.K. band's 24-song set at the American Airlines Arena included "King of Limbs" session tracks "Staircase" and "The Daily Mail," "OK Computer"-era instrumental B-side "Meeting in the Aisle," and two completely new songs. Watch performances of the previously unheard tracks -- "Identikit" and "Cut a Hole" -- below.

With syncopated beats punctuating polyrhythmic chaos, "Identikit" fits in line with recent entries in Radiohead's increasingly electronic-focused discography. However, the song's competing vocal lines are something sort of new for the band, suggesting that when (or rather, if) "Identikit" finds its way onto an album, it will likely stand out.

"Cut a Hole," on the other hand, is a downbeat, piano-tinged offering, on which frontman Thom Yorke really wallows vocally in whatever's ailing him this time.

Radiohead's "King of Limbs" Tour continues tomorrow in Tampa, with U.S. tourdates across the south and the west scheduled through April.
