Lady Gaga has spent much of the past two years hanging out with Tony Bennett and making amiable throwback big-band music. But in January, she contributed a big, searching orchestral power ballad called “Till It Happens To You” to The Hunting Ground, a documentary about campus rape and sexual assault. Power ballad specialist Diane Warren wrote the song, and it treats a very important topic with big, cinematic emotional power. Catherine Hardwicke, the filmmaker behind Thirteen and the first Twilight movie, directed a stately black-and-white video for the track. Nikki Reed costars, but Gaga herself doesn’t appear in the video. Instead, it focuses on the stories of a few women who go through terrible things at college, with a special emphasis on how they can find help. Watch it below.

“Till It Happens To You” is out at iTunes now, and proceeds from its sales go to benefit organizations helping survivors of sexual assault.
