Hans Zimmer has composed a new song, called "Aurora", which is dedicated to those who were affected by the tragic events in Aurora, Colorado. More details about the song can be found on his Facebook page. You can either purchase the track on iTunes, or you can donate a minimum of 10 cents for the track here. All proceeds will be donated to the Aurora Victim Relief organization. This just goes to show how classy Hans Zimmer is.
The track itself is a beautiful, yet haunting blend, of choral singing mixed with slow themes of "Rise" from The Dark Knight Rises soundtrack. Definitely donate to this wonderful cause.
