Wilco [ tickets ] has tacked a multi-night residency at Chicago's Riviera Theatre onto its upcoming tour slate, and frontman Jeff Tweedy has announced plans to play a January benefit show in the same city.

The group's Chicago engagement covers five dates over Feb. 15-20, with the shows "exploring the band's complete recorded works," according to a press release. Pre-sale tickets are available through Wilco's official website.

Tweedy, meanwhile, will play a solo acoustic show Jan. 26, also in the singer's hometown of Chicago, to provide youth scholarships. Tickets will run $100 apiece, and are currently on sale to the public.

Wilco, which continues to back this year's "Sky Blue Sky," has nine other cities on its early 2008 schedule, including a Feb. 22 show in Cleveland following the Chicago residency. All dates are below.

"Sky Blue Sky," the band's seventh studio album, follows 2004's "A Ghost is Born." The group self-produced the new set in its own Chicago studio, with TJ Doherty (Sonic Youth, The Hold Steady) handling recording chores and Jim Scott (The Red Hot Chili Peppers, Dixie Chicks) doing the mixing.

The album arrived on The Billboard 200 album chart in the No. 4 spot, marking the band's highest debut ever.

The disc helped Wilco nab its fourth Grammy nomination earlier this week, receiving a nod in the Best Rock Album category. The band, which has now received four Grammy nominations overall, scored two trophies with 2004's "A Ghost is Born," which took home wins for Alternative Rock Album and Best Recording Package.
