It's taken several weeks for Wilco [ tickets ]'s fall tour to take shape, but the outing has grown into a 25-plus city affair that spans three months.

The latest round of dates focuses on the western U.S., and extends the trek well into November. Calexico [ tickets ] will support Sept. 14-18, and The Fiery Furnaces [ tickets ] will be on the bill Sept. 27-Oct. 6. Ticket pre-sales are being offered for some shows; details are available at Wilco's official website.

Wilco's latest album, "A Ghost is Born," hit stores in June. The band co-produced the set with Jim O'Rourke, who engineered the group's previous release, 2002's "Yankee Hotel Foxtrot."

Fans who purchase "A Ghost is Born" can use the CD's enhanced features to access via the band's website a live recording of a recent Wilco show at Chicago's Vic Theatre.

Joining Wilco's touring band this year are keyboardist/guitarist Pat Sansone (The Autumn Defense) and guitarist Nels Cline. Earlier this year, multi-instrumentalist Leroy Bach, who officially joined the band before the release of 2002's "Yankee Hotel Foxtrot," departed. Programmer/keyboardist Mikael Jorgenson has since taken over Bach's slot.

The only remaining original members of Wilco are frontman/guitarist Jeff Tweedy and bassist John Stirratt. Drummer Glen Kotche replaced Ken Coomer before "Yankee Hotel Foxtrot" was recorded, and multi-instrumentalist Jay Bennett exited after "Yankee Hotel Foxtrot" was completed.
