Best known for setting up their own reportedly groundbreaking label and distribution deals for the release of their 2007 debut album, Enter Shikari are now confident enough to predict that their second will turn out to be the definitive recession-Britain record. Quite possibly it won't. But, however shrieky and unwieldy, the album merits respect for hammering home earnest polemics about "people power" and doing it with more musical imagination than the similarly inclined Enemy. Though the band err too generously on the side of screamo-metal - especially on the likes of Hectic, which alternates screeching vocals and dreamy acoustic passages - they also incorporate jazz (The Jester), Ibiza rave (Solidarity) and gormless, endearing rapping (Zzzonked). There's a great deal going on here, but the message, inelegantly spelled out in No Sleep Tonight, is clear enough: "I'm thinking what's the deal/ With the facts that they conceal?/ And I'm thinkin' what's the hummin'/ Bit of rhetoric and chummin'?"
