As if my anticipation for The Dark Knight Rises couldn't get any higher, you can now preview 30 second samples of the soundtrack for the movie here. The soundtrack will be released on July 17th, and was composed by Hans Zimmer, who was co-composer (with James Netwon Howard) of the soundtracks for the previous two Nolan bat-movies, as well as Nolan's Inception. I would also keep an eye on The Dark Knight Rises Facebook page, as they will be releasing more previews in the coming weeks leading up to the movie. Just from the 30sec clip, "Imagine the Fire" sounds like it could be pretty epic.
I'm really looking forward to hearing the whole thing when it is released, since the soundtracks for Batman Begins, The Dark Knight, and Inception have been some of Zimmer's best work.
