The band just concluded a European tour during which they performed in Switzerland, Italy, Spain and France.

While touring the U.S., Porcupine Tree will make their way through the East hitting up New Jersey, Massachusetts, New York and Pennsylvania along the way. From there, they’ll travel through the Midwest, eventually landing on the West Coast.

Some gigs include the House of Blues in Cleveland May 25; Boulder, Colo.’s Fox Theatre June 1; and The Fillmore in San Francisco June 8.

Former King Crimson guitarist Robert Fripp will open for Porcupine Tree on various West coast dates. Additional openers are still in the works.

Porcupine’s current lineup -comprising singer/guitarist Steven Wilson, Richard Barbieri on keyboards, Colin Edwin on bass, and drummer Gavin Harrison – has been together since 1993. Along with its success on the British indie charts, the band also has a reputation as a pioneering underground force in the U.K.
