Rumors were rippling early this week that Soundgarden frontman Chris Cornell was set to release a new track.

Rumors can go either way, but in this case, what you heard is true.

Cornell has just shared a new song called “The Promise” which was written for the new Christian Bale movie of the same name that focuses on the Armenian genocide that spanned from 1915-1923.

Of the song, Cornell told Rolling Stone: “There are a couple of really amazing documentaries about the Armenian genocide, and one of them was about the phenomenon that people who had literally minutes to grab what they could from their homes would take photos before anything else — before jewelry even. I was really moved by that; the idea of what is most important to people in a crucial second.

The Terry George-directed film will be out April 21.
