The Foo Fighters [ tickets ] will perform a free concert at the former Walker Air Force Base in Roswell, NM--where legend has it the U.S. government stored evidence from the 1947 crash of an unidentified flying object--for winners of a contest in celebration of the band's 10th anniversary and upcoming album.

About 500 contest winners will be flown to Roswell via chartered planes to attend the barbecue and Foo Fighters concert. The contest is sponsored by RealNetworks' Rhapsody music service; more details are at Rhapsody's website.

Foo Fighters frontman/guitarist Dave Grohl named the band after the unidentified glowing balls that Allied and German pilots reported seeing at night during World War II and dubbed Foo Fighters (after a comic strip of the era). He named his record label Roswell Records.

"This is a long overdue and historic moment for this band," Grohl said in a statement. "Despite being in a band called Foo Fighters, having a label called Roswell Records, and being a total UFO nut, I have never been to Roswell, NM. So the fact that we finally get to go to Roswell and play a gig in the same hangar where they allegedly stored the remains of the 1947 UFO crash blows my mind."

Foo Fighters release their fifth album, "In Your Honor," on June 14. Disc One is described in a press release as containing "some of the heaviest, loudest material the band has ever recorded." Disc Two is "comprised of largely acoustic, subtly laid back songs with guests ranging from Led Zeppelin's John Paul Jones to Norah Jones."

The Foo Fighters have also scheduled several events in Toronto for June 16, starting with an acoustic set at the studios of radio station 102.1 The Edge at 5 p.m., a subsequent autograph signing at the flagship HMV store on Yonge Street, and a 10 p.m. concert at Lee's Palace.

The new Rhapsody 25 music service will be streaming all five Foo Fighters albums for free, beginning June 14.
