Enter Shikari are a British post-hardcore band. This was the title track of their sophomore album.
This is a poem read by the father of drummer Rob Rolfe. Frontman Rou Reynolds explained to Kerrang! May 2, 2009: "We wanted a War of the Worlds type voiceover and he had the perfect voice for it. It's really low and menacing. He talks like that all the time!" Reynolds added that the grandfather of bassist Chris Batten "recorded part of it, too. To give a sense of global unity, we asked fans to submit recordings of them saying 'we must unite' in different accents and languages. It was great to hear everyone's contributions."
