The Dark Knight Rises composer Hans Zimmer has released a new track, titled "Aurora," on his Facebook page to help raise money for victims of last weekend's massacre in Aurora, Colorado. "'Aurora' is dedicated to those who lost their lives and were affected by the tragedy in Aurora, Colorado," writes Zimmer. "I recorded this song in London in the days following the tragedy as a heartfelt tribute to the victims and their families."

The track is available for donations ranging from 10 cents to $2,500 and can be downloaded here. All proceeds will benefit the Aurora Victim Relief Organization.
