Soundgarden will release their first collection of music since 1996 in the form of Telephantasm on September 28th in the US and September 27th internationally. This multi-label, career-spanning retrospective album includes beloved band hits, deep back catalogue cuts and a never-before-heard unreleased track entitled "Black Rain," taken from the Badmotorfinger recording sessions. Telephantasm marks the first time ever a collection of its kind has been collated in one place.

Like the iconic '60s and '70s bands which inspired them, Soundgarden redefined rock music for a whole generation and had a revolutionary impact on the course of musical history. As one of the first bands to release music on the venerated Sub Pop label, and the first band to come out of the 90's Seattle music scene to later sign to a major label, they are once again making history with Telephantasm. The band has announced that they will be partnering with innovative gaming publisher Activision Publishing, Inc. to release the album on September 28th via A&M/UMe inside 1 million copies of the new videogame Guitar Hero: Warriors of Rock. This release marks the first time a music album will be simultaneously released and bundled with a video game launch.

All North American Guitar Hero: Warriors of Rock launch units will contain the 12-song retrospective disc and will be exclusive to Guitar Hero: Warriors of Rock for one week (until October 5). Additionally, fans will get full access to the band's new album as downloadable content for Guitar Hero: Warriors of Rock day and date with the launch of the game. The 12-song disc will then be available on October 5th at all music retail outlets and on the band's web site www.soundgardenworld.com.

"We are thrilled about the exclusive and trailblazing partnership between Guitar Hero: Warriors of Rock and Soundgarden," said David Haddad, Chief Operating Officer, Guitar Hero. "The fact that this seminal band chose Guitar Hero: Warriors of Rock as the way to reintroduce themselves speaks volumes about Guitar Hero's ability to deliver music, in an exciting, interactive way, to millions of music fans and gamers. The extensive collaboration – bundling Telephantasm with Guitar Hero: Warriors of Rock, including the unreleased "Black Rain" as an exclusive in the game and releasing the entire album as downloadable content – demonstrates Soundgarden's and Guitar Hero's commitment to delivering a great experience for its fans."

Additionally, on September 28th A&M/UMe will be releasing 3 expanded versions of Telephantasm which will include a double-disc with 12 additional tracks, 5 of which are previously unreleased, and Soundgarden's first-ever DVD, featuring 20 videos, 13 of which have never been released, a Deluxe 3-LP Vinyl Edition and an individually numbered Super Deluxe Collector's Edition. The Super Deluxe Collector's Edition will be available for a limited time and will include 2 CDs, the limited edition DVD, three heavy vinyl discs, a collectible poster, lithos, and much more. These 3 expanded versions will be available at all music retail outlets and on the band's website.

On April 16th 2010, Chris Cornell, Kim Thayil, Ben Shepherd and Matt Cameron of Soundgarden took to the stage together for the first time in 12 years at the Showbox Theater in Seattle. Playing songs from their celebrated and acclaimed catalogue, the result was nothing short of brilliant and saw the four band members playing with the same heart and vigor for which they have always been known. On August 8th, Soundgarden will hit the stage again, headlining Lollapalooza in Chicago's Grant Park, preceded by a sold-out show at the Vic Theatre on August 5th.
