Composer Hans Zimmer recently posted this on his Facebook page:
"Aurora" is dedicated to those who lost their lives and were affected by the tragedy in Aurora, Colorado. I recorded this song in London in the days following the tragedy as a heartfelt tribute to the victims and their families. 100% of the proceeds will be donated to Aurora Victim Relief organization. The track is available on iTunes shortly and here: http://bitly.com/QmUiWM"
Just as Christian Bale's visit was, this is a great gesture of sensitivity and support, so donate, help, and listen.
