Guitarist Tom Searle told HMV.com
the story of this song: "I was soundchecking when we were on the Warped Tour
and I got my guitar out of the case and started playing and thought 'F--k, that sounds heavy,'" he recalled. "Turns out my guitar had been knocked out of tune and a string had come loose. After I played the show, I put it back in that mode and came up with the riff."
