Another batch of shows have been confirmed for the upcoming co-headlining tour featuring fellow alt-rock mainstays Foo Fighters [ tickets ] and Weezer [ tickets ], and additional dates are in the works.

Seven new October shows--in Champaign, IL; Detroit; Cleveland; Fairfax; Philadelphia; E. Rutherford, NJ; and Oakland, CA--are the latest additions to the outing. Ticket on-sale information, culled from the Weezer and Foo Fighters websites, is below.

More dates will be announced. Last month, the Foo Fighters [ tickets ]' publicist said the tour is also expected to touch down in Grand Rapids, MI; Baltimore; Worcester, MA; Fresno, CA; and Portland, OR.

Foo Fighters released their fifth album, the two-disc set "In Your Honor," in June. Disc One features hard-edged rockers, while Disc Two largely houses acoustic tracks.

Weezer [ tickets ] is backing its new LP, "Make Believe," which hit stores in May and debuted at No. 2 on The Billboard 200 album chart.

Foo Fighters recently completed a brief Canadian tour. Weezer, meanwhile, wrapped up a three-week North American tour at Lollapalooza in Chicago last month.
