Seattle folk-rock heroes Fleet Foxes will launch their 2009 North American tour May 25 at the Sasquatch! Music Festival at The Gorge.

The tour will visit Washington, D.C.; Philadelphia, Montreal, Toronto, Chicago, Minneapolis and other cities in July and August. The Chicago date is an appearance at Lollapalooza.

A ticket pre-sale begins Wednesday, May 6, at 10 a.m. at Ticketmaster.

The tour is sure to raise the profile of one of Seattle’s most exciting young bands.

On Tuesday, May 5, on Sub Pop Records, the band releases its “Mykonos” seven-inch single packaged in a “gatefold” sleeve and backed with a previously unreleased (at least in the U.S.) version of the folk ballad “False Knight on the Road,” a song popularized by Steeleye Span and Richard Thompson. “Mykonos” is from the band’s beautiful “Sun Giant” EP on Sub Pop.
