The Florence Welch-fronted band have written and recorded 'Breath of Life' for the upcoming Snow White and the Huntsman soundtrack.
Previously talking about recording the track, Welch explained: "We went in and demoed the track, these big, clattering drums, huge bass sounds and everything was very intense... and then we sent that to the guys in LA who composed it.
"It was amazing to see the music we played being turned into this amazing orchestral thing."
She added: "You feel in a bit of a way like you're kind of making it up as you go along, and then when you see it done, laid out before you in such a beautiful, orchestral fashion, it's really incredible.
"I love choirs and I love choral music, and there was a 60-piece choir singing the vocal parts that I had written. When the baritones came in, I nearly wept, it was so emotional."
Snow White and the Huntsman stars Kristen Stewart, Charlize Theron and Chris Hemsworth, opening on June 1 in US and UK cinemas.
The official soundtrack will be released on May 28 in the UK and May 29 in the US with the full tracklist yet to be confirmed.
