The tour, dubbed The Rout Of The Patagons, will launch with two shows at the Crystal Ballroom in the Decemberists’ hometown of Portland, Ore., October 17-18. They’ll also do double duty in Washington, D.C., with two gigs at the 9:30 Club at the end of the month.

Lavender Diamond will open the first half of the tour, dropping off after a November 1 show at Philadelphia’s Electric Factory. Alasdair Roberts will take over two days later at the Hammerstein Ballroom in New York City.

The tour will wind back across the continent to finish at the Commodore Ballroom in Vancouver, B.C., November 18.

The Crane Wife, due out October 3, is the Decemberists’ first album for Capitol Records. The band’s previous three full-lengths were released on Kill Rock Stars.

“There was a real strong sense among the band that we were not going to try to make a record that someone would typically make for a major label,” frontman Colin Meloy said. “In some ways I think it pushed us farther to the left, farther out of the Decemberists comfort zone.”

Lavender Diamond has yet to release a full album, but the folky Los Angeles act has been building buzz in recent months and made a splash at this year’s South by Southwest conference in Texas.

Scottish singer/guitarist Alasdair Roberts recently finished recording a new solo effort, although no release date is set. The former Appendix Out leader will play several U.K. festivals this August.
