While festival-goers in Chicago have a lot to look forward to at this upcoming weekend's Lollapalooza, the hottest ticket in town and possibly most anticipated act of all won't be at Grant Park. Them Crooked Vultures, a long-rumored collaboration between Queens of the Stone Age's Josh Homme, Foo Fighter Dave Grohl and former Led Zeppelin multi-instrumentalist John Paul Jones, is set to stage its first ever show at the celebrated rock club Metro.

Tickets will be on sale via Etix starting Thursday morning at 10 a.m. The show time is listed as 11:59 p.m. on Sunday.

Grohl revealed the idea four years ago in an interview with British music magazine Mojo, sayng only that he'd be on drums, with Homme and Jones on guitar and bass respectively. Antiquiet.com recently pressed Homme's wife for confirmation of the project and is reporting that the band is currently recording in Los Angeles.

Details about the hard rock supergroup's work are scant, but the lineage is quite clear. Jones and Grohl have worked together many times before, including two tracks on the Foo Fighters' 2005 release "In Your Honor" as well as joining the Foo Fighters on stage in June 2008 at Wembley Arena. Grohl lent his drumming talents to Queens of the Stone Age's 2002 release "Songs for The Deaf."

Lollapalooza 2009 kicks off this Friday (August 7) with Jane's Addiction, Tool, Depeche Mode, The Killers and Kings of Leon headlining throughout the weekend.
