"The Dark Knight Rises" composer Hans Zimmer has composed a song dedicated to the Aurora, Colorada shooting victims.
Zimmer posted the track "Aurora" on his Facebook page yesterday.
Zimmer said he recorded the song in London in the days after the theater shooting last week.
All proceeds are being donated to a fund for victims of the shooting that killed 12 people.
Zimmer has scored all three films in Christopher Nolan's Batman trilogy.
