Conan O'Brien made his debut last night as the host of The Tonight Show, replacing Jay Leno after his 17-year tenure. The stars of the show? The towering Irish funnyman, Will Ferrell, and Seattle alt-rock fivesome Pearl Jam, who unveiled "Get Some," a brand new song off their fall release, Backspacer!

Pearl Jam will release their new album, tentatively titled Backspacer, early this fall. Hey, it only took three years and cost bassist Jeff Ament $3,000 in cash, his passport, and a few head lacerations -- it must be awesome!

The ever wittastic Conan O'Brien will begin his reign as the host of NBC's Tonight Show June 1 (11:35 p.m.), and he's invited some musically-inclined pals along to join the party -- and we're not talking about the White Stripes.

Pearl Jam bassist Jeff Ament was robbed and assaulted outside Southern Tracks Recording studio in Atlanta, GA, where the Seattle alt-rock band is recording their new album.

This week, Eminem's new single, "3 A.M.," leaked -- as did a teaser video for the gory song, along with more details about his May 19 record, Relapse. Meanwhile, SPIN reviewed Green Day's 21st Century Breakdown (May 15), as the band defended their classic-rock ambitions and punk rock roots.

The lineup for the eighth annual Austin City Limits music festival has been announced, and it's a doozy -- packed with 130 bands, including headliners Pearl Jam, Dave Matthews Band, and the Beastie Boys. The fest will hit Austin's Zilker Park October 2-4.
