Indie rock titans the Decemberists are gearing up for a spring trek that will hit 1,500- to 3,000-capacity venues across the United States. The outing follows the success of the act's Capitol Records debut, "The Crane Wife," which has sold 151,000 copies in the U.S. since it's October release, according to Nielsen SoundScan.

The tour launches with a two-night stand at Jersey City, N.J.'s Loews Theater March 21-22, and wraps at Western Washington University in Bellingham on May 5. The band will also perform at this year's Coachella Valley Music & Arts Festival on April 28. The three-day event at Indio, Calif.'s Empire Polo Field announced its preliminary lineup today (Jan. 22).

Supporting on all dates (except April 4-6) is My Brightest Diamond.

Following the release of "The Crane Wife," the Decemberists took to the road in November and December, performing in ballrooms and theaters. Eighteen shows reported to Billboard Boxscore reveal the Portland, Ore.-based band grossed $695,763 and saw nearly 32,000 concertgoers in attendance. It's a significant jump from 2005, when the act grossed $361,570 for 22 reported gigs, according to Boxscore.

Along with growing box-office numbers, the act has seen an increase in album sales. Thus far, according to SoundScan, "The Crane Wife" has moved 9,000 more units than 2005's "Picaresque," which was released via Olympia, Wash.-based indie Kill Rock Stars.

"Their fans are really enthusiastic. A lot of bands can have the same amount of records sales but won't necessarily draw the crowds they do," North American agent Kevin French of Bigshot Touring Artists tells "The people who buy their records are really fans. They have a great live following."

For its upcoming tour, which starts one month after a three-week European jaunt, the Decemberists will explore uncharted territory Stateside, according to French. Ticket prices for the U.S. trek range from $20 to $30.

"We have missed some of the smaller markets on the past tours, so this time we're putting thought into places we've never been before," he says, citing such cities as Memphis, Tenn. and Milwaukee. "The record is doing great everywhere, so we have to get to every city."

"With their schedule, the band is so busy and there've been a couple of babies born, so we can't stay out as long as some bands can," he continues. "Some bands are out there for 10-week tours. We like to try and keep it at about five weeks or so. We normally hit the major U.S. cities, and end missing the Knoxville's and Memphis'."

Future touring plans include "a couple of the major festivals," which French declined to reveal at press time, along with a summer outing that could include amphitheater dates.

The Decemberists is managed by Dawn Barger at Big Hassle.
