In the wake of multi-instrumentalist Leroy Bach's recent departure, Wilco has confirmed two new members to join the band on tour this spring. Filling in on keyboards and guitar will be Pat Sansone, who has released two albums with Wilco bassist John Stirratt as the Autumn Defense, while veteran axeman Nels Cline will join in on guitar.

The new lineup will debut April 21 in Columbia, Mo. Beyond previously announced appearances at the Superfly During Jazzfest series and the Coachella and Bonnaroo festivals, Wilco will also play late April shows in Austin, Texas, Santa Fe, N.M., and Flagstaff and Tucson, Ariz., with support from Giant Sand's Howe Gelb. The lone international date at present will come May 28 at the Primavera Sound festival in Barcelona.

Wilco is gearing up for the release of its next studio album, "A Ghost Is Born," due June 8 via Nonesuch. It's the follow-up to 2002's acclaimed "Yankee Hotel Foxtrot," which debuted at a career-best No. 13 on The Billboard 200.
