Prior to its headlining appearance at Bonnaroo, Radiohead will embark on a short theater tour of Europe. After spending much of the past two years in the studio, the group is expected to rework its newest material for a live setting and, possibly, release additional material exclusively through the web. As of now, Radiohead’s tour is scheduled to kickoff in Copenhagen, Denmark at the KB Hallen and continue through Mid-May. At present, Bonnaroo remains the bands only announced U.S. date.
