It’s been an excruciatingly uncertain four-year wait for Bloc Party fans, as Kele ‘red herring’ Okereke dropped straight-faced hint after straight-faced hint about the band’s demise, but the indie mavericks are finally back, brandishing the first taster from their game-changing new album Four. ‘Octopus’ presents the sound of a band simultaneously moving forward and digging into their back catalogue, combining the frantic guitars of ‘Helicopter’ and the pop sensibilities of ‘Banquet’ with a newfound ruggedness that we’re delighted to confirm features heavily throughout their comeback 12-tracker.
