The sixth studio set for the Jeff Tweedy-fronted band is less experimental and adventurous than Wilco's previous few efforts. It is the first Wilco studio album to feature the work of touring guitarist Nels Cline.

If the concept of "The Beatles, remixed" saddens you, know that original Beatles producer George Martin was at the helm for this project, which serves as the soundtrack to the Vegas-based Cirque du Soleil show of the same name. The 26 mashed-up tracks here were augmented with additional instrumentation and vocals performed by The Beatles themselves, culled from hours of original demo and master tapes, with pieces of 130 songs ultimately represented in some form.

This "green album," produced by Ric Ocasek, is actually the second untitled album for the Los Angeles band, not to be confused with 1994's "blue album." The album is the band's first since leader Rivers Cuomo's graduation from Harvard -- in fact, it is their first since their 1996 sophomore effort, 'Pinkerton,' which alienated some fans with a shift toward an angrier sound.

A reissue of the band's 1972 double album is long overdue, as Exile captures a time when they became one of the greatest rock-and-roll bands in the world.

This double-disc set from Dave Grohl & co. includes one full CD of acoustic tracks. Guests include John Paul Jones, Norah Jones, Josh Homme and Petra Haden.
