This track is a collaboration with Swedish death metalers In Flames, who have been a favourite of Pendulum lead singer Rob Swire since high school. Swire told The NME
January 16 2010: "Me and Gareth (McGrillen) have been talking a lot about doing a track with proper metal vocals. It's melodic and leaning towards a death metal-style. We experimented with that style of guitars on the live version of the Coldplay track we did ("Violet Hill
"), but this is much heavier."
