Radiohead kicked off their 2012 world tour Monday night (Feb. 27) at Miami's American Airlines Arena with a sprawling, 24-song set that focused on last year's 'King of Limbs' album, yet managed to touch on tunes from the band's catalog spanning all the way back to their breakthrough 1997 release, 'OK Computer.'

With 'King of Limbs,' Thom Yorke and the boys figured they had managed to record an album that could not be performed live, do to its extremely complex polyrhythms and reliance on piles of vintage gear. But Radiohead at least managed to solve that first problem with the addition of Clive Dreamer of trip-hop icons Portishead, a drummer with a studious jazz background -- not to mention an uncanny resemblance to long-running Radiohead skinsman Phil Selway.

Dreamer made his live debut with the band last fall with an appearance on 'Saturday Night Live' and a handful of New York ballroom shows, and has since become much more than an hired gun extra in the band. He now performs on several old numbers, and even has helped compose two new tunes that the group debuted during the Miami show -- part of an impressive list of 75 songs that the band worked up to possibly perform on tour.

Dreamer's contributions to the two new songs that appeared on the Miami setlist -- 'Identikit' and 'Cut a Hole' -- both perhaps hint at the direction the band may be taking in the near future.

Radiohead have North and Central American tour dates scheduled through an April 21 gig at the Coachella Festival in Indio, Calif., followed by a June 8 appearance at the Bonnaroo festival in Manchester, Tenn. After that, the band heads back overseas for headlining and festival dates in Europe and beyond that are scheduled on-and-off through a Nov. 16-17 stand in Melbourne, Australia.
