Sheryl Crow has been joined by a host of stars in the making of her as-yet-untitled, self-produced fourth Interscope/A&M album, but the artist's manager tells Billboard.com that the tracklisting has not yet been finalized. Among the guests who have put prospective tracks to tape with Crow include Stevie Nicks, Don Henley, Lenny Kravitz, the Dixie Chicks' Emily Maines, Emmylou Harris, and Liz Phair. The latter's collaboration with Crow, "Soak up the Sun," has made the final cut and is likely to be the album's first single.

As previously reported, among the other guests on the set are guitarist Doyle Bramhall II and bassist Mike Elizondo, known for his work with Dr. Dre. Some material was co-written with Jeff Trott, who previously worked with Crow on the hits "Everyday Is a Winding Road" and "If It Makes You Happy," as well as the bulk of the 1998 album "The Globe Sessions."

Songs that have been recorded include "It's So Easy" (with Henley), "You're An Original" (with Kravitz), "Abilene" (with Maines), and "Weather Channel" (with Harris). Look for the new set -- which features backing by guitarist/bassist Tim Smith, guitarist Peter Stroud, violinist Lorenza, cellist Matt Brubeck, and drummers Jeremy Stacey and Steve Jordan -- to hit stores in late March or early April, with a tour to follow.

While recording was underway at Nashville's Emerald Sound Studios, Crow was also interviewed for an upcoming episode of VH1's "Behind the Music," the debut of which has not yet been scheduled.

Fans can also hear Crow dueting with Willie Nelson on the latter's new Lost Highway album "The Great Divide," as well as covering the Beatles' "Mother Nature's Son" on the V2 soundtrack to the film "I Am Sam."
