Activision and Def Leppard have partnered to release a three song track pack for Guitar Hero III: Legends of Rock.

The track pack will include the unreleased single ‘Nine Lives’ and Guitar Hero fans will get to play it before the band’s release of their new album.

The track pack will be available on Xbox Live Marketplace on the 24th of April and on the PlayStation Store in early May. It will also include live versions of Def Leppard’s ‘Photograph’ and ‘Rock of Ages.’

“Being involved with Guitar Hero is very exciting for us and adds a whole new layer of appreciation,” says Joe Elliott, lead singer, Def Leppard. “I know from personal experience how much more you get into the music by playing the game - which is why we were keen to explore this opportunity.”

“Guitar Hero is extremely popular with all kinds of music heads, which includes a lot of our fans - and we think releasing ‘Nine Lives’ this way first is just fantastic!”

“We are extremely thrilled to be partnering with Def Leppard, who are true rock icons,” said Dusty Welch, Head of Publishing for RedOctane.

“The band’s participation in offering ‘Nine Lives’ to fans exclusively via Guitar Hero III downloadable content before their album hits store shelves, before the single is available for purchase on iTunes, demonstrates the level of commitment these legendary artists are making to Guitar Hero and how the franchise is transforming the music landscape.”
