Soundgarden's first brand new song in nearly 16 years has arrived! Check out 'Live to Rise' from 'Avengers Assemble' -- the soundtrack to the upcoming Marvel mega-blockbuster -- right here.

'The Avengers' is expected to be one of the biggest films of the year...possibly the decade. Marvel began setting the stage for this massive project years ago with Avenger-related sub-plots running in previous films like 'Iron Man,' 'The Incredible Hulk,' and 'Thor.' The movie, due in theaters May 4th, has a star-studded cast -- it only makes sense that they would draft an impressive list of artists for the soundtrack.

The 'Avengers Assemble' album will feature music from some of rock's biggest names including Five Finger Death Punch, Evanescence, Shinedown and Bush, but the true headliner is Soundgarden.

The band will include their song 'Live to Rise' as part of the collection, a new song the band wrote specifically for inclusion in the film. This is the first indication of what we can expect on the band's new album, their first since 1996's 'Down on the Upside.' Soundgarden's sixth album was initially expected this spring, but recent statements from the band indicate a fall 2012 release.
