As the band continues to ride the success of last year's "Narrow Stairs," its best-selling effort to date, Death Cab for Cutie [ tickets ] has mapped spring tour plans.

Following a March 7 appearance at Miami's Langerado Festival, the band will kick off the spring trek April 7 in Upper Darby, PA. The 20-date tour, which includes a number of college campus shows, extends through early May. Details are included below.

Indie-rockers Ra Ra Riot [ tickets ] will offer opening support for all shows, with Cold War Kids [ tickets ] providing additional support during the April shows, and singer/songwriter Matt Costa [ tickets ] adding support for the dates in May.

Death Cab continues to back last spring's "Narrow Stairs," which sold 144,000 copies during its first week in stores and earned the band its first No. 1 album. The set--the band's first studio effort since 2005's Grammy-nominated "Plans"--was produced by Death Cab's guitarist, Chris Walla; the album's first two singles, "I Will Possess Your Heart" and "Cath...," are streaming at the band's MySpace page.

"The landscape of the thing is way, way more lunar than the urban meadow sort of thing that has been happening for the last couple of records." Walla told a Billboard interviewer last year of the record, "[It's also] louder and more dissonant and ... I think abrasive would be a good word to use."

Recently, the band's "Grapevine Fires" (from "Narrow Stairs") was picked as one of the songs to be included on the official album of Barack Obama's inauguration. The disc, titled "Change Is Now: Renewing America's Promise," will also include tracks from Will.I.Am, Wilco, Lenny Kravitz and others. More information can be found at Death Cab's website.
