Bass & Mandolin, the second recording collaboration by bassist Edgar Meyer and mandolinist Chris Thile, is due out next Tuesday, September 9, on Nonesuch Records. But you don't need to wait till then to hear it. The new album of original tunes, which comes six years after their recording debut as a duo, Edgar Meyer & Chris Thile, is streaming in full this week as a Check Ahead feature from NPR member station WNYC's Soundcheck at wnyc.org.

"Bass & Mandolin features a constant give and take between melody and accompaniment," says Soundcheck's Katie Bishop. "More than anything, it's easy to hear how much fun these two have playing together. Both of the duo's albums are filled with songs flavored by a back-and-forth, bet-you-can't-catch-me playfulness and humor that can only come of the tightest musical relationships. On Bass & Mandolin, that relationship is a little older and a little wiser—and sounds all the more comfortable and relaxed for it."

To pre-order Bass & Mandolin, head to iTunes or the Nonesuch Store for an instant download of the album track "Tarnation."

Bass & Mandolin, says The Bluegrass Situation's Cameron Matthews, "is about to set the bluegrass and classical realms on fire." Thile and Meyer joined The Bluegrass Situation and Mason Jar Music during a recent visit to Telluride, Colorado, to perform a track from the new album, "Why Only One?," for a Mountain Session, which you can watch below.
