A new rock-packed soundtrack for next month’s Marvel super-team spectacular The Avengers is scheduled for release three days before the movie opens (you can pre-order Avengers Assemble here), but no U.S. date has been set for a release of the film’s orchestral score composed by Alan Silvestri.

Amazon’s UK site has the Avengers score being released on April 20 and has posted brief snippets from all 18 tracks of the album. You can check out a preview of Silvestri’s score here.

It is exactly what you would expect an Alan Silvestri score for a grand-scale summer blockbuster to be, a rousing action score meant to generate excitement and radiate emotion. I can’t wait to hear the score in its entirety and see it matched to the Joss Whedon-director superhero adventure on the biggest of movie screens.

The Avengers opens on May 4, 2012.
