Slipknot's Jim Root sounds properly fired up about what's coming next, and fair play to him for being so candid about the last record. If the band are genuinely looking to shake things up rather than coast on past glories, that's the kind of attitude that keeps heavy music interesting and stops artists becoming parodies of themselves. Of course, whether a new Slipknot album actually lands with listeners or ruffles feathers in the way Root intends remains to be seen, but we're intrigued to hear what they've got brewing.
