Singer/guitarist Jared Leto told Musicradar.com
about the song: "This was very interesting for me as a writer in that I sat down with a very pointed and decisive intention. Usually songwriting can be very obtuse and roundabout way of getting in touch with your feelings. With this one, I knew exactly what I wanted to do and I knew it was going to be the album opener. The song is about freedom. It's about beginning a battle and deciding that you've had enough and you're willing to go to war to fight for what you believe in."
