After playing only two small U.S. shows in support of last year’s Kid A, Radiohead is about to embark on their first full-fledged North American tour in three years.

Rock’s favorite anti-stars will begin a tour of outdoor venues on June 18 in Spring, Texas, just north of Houston. That date and a handful of other stops have been public for awhile, but 11 more shows in the Atlanta, Chicago, Toronto, Montreal, Philadelphia, Washington D.C., Boston, NYC and Los Angeles areas have been confirmed by Capitol Records. One more date, in Cleveland, is expected to be announced soon.

The first leg of the tour wraps June 30 in Santa Barbara, Calif., and then the band heads back to England to play a benefit show in their hometown of Oxford.

Radiohead’s North American outing resumes July 30 in Atlanta and runs through August 20, when Thom Yorke, Jonny and Colin Greenwood, Ed O’Brien and Phil Selway say goodbye to the New World with a concert at the Hollywood Bowl.

Scotland’s much-hyped Beta Band – who’s eclectic stylings were popularized in the U.S. by the John Cusack movie “High Fidelity” – are expected to open on all dates.

It looks like more international dates for Radiohead will come to light shortly. September concerts in Germany and Northern Ireland appear to be in the works, and shows will likely be added to the band’s fall tour of Japan.
