Trek expected to be underway in September.

Modern rock heavyweights Foo Fighters and Weezer are in talks to team for a fall tour, Foos leader Dave Grohl said this morning (June 14) on "The Howard Stern Show." The trek is expected to get underway in September, although sources say details may not be finalized until next week.

The Foos' new double album, "In Your Honor," hits stores today. The group's only two scheduled North American shows will come Thursday (June 16) in Toronto and Saturday at Walker Air Force Base in Roswell, N.M., where it will entertain an invite-only crowd of winners of a contest sponsored by online music service Rhapsody.

"I can't wait until I'm stuck on a bus, watching 'Office Space' for the millionth time and eating a pizza in Utah," Grohl recently told Billboard about his excitement to return to the road. "That's my perfect day."

Beginning July 1 in St. Gallen, Switzerland, the band will hit the European festival circuit. It will also play July 29 at Japan's Fuji Rock Festival.

Weezer is in the midst of its own European tour that plays London tonight. The group will begin a summer run July 2 in Las Vegas, as part of the city's 100th birthday celebration. The group's new Geffen album, "Make Believe," is No. 17 in its fourth week on The Billboard 200.

Both acts are booked by Don Muller at Creative Artists Agency.
