This live concert filmed at the Astoria in London is one of the very best examples of how to capture not only a live performance generally, but the unusual dynamics of a ferocious, nine-piece metal band. Filmed with many cameras, some even attached to the instruments and masks, you get to feel like you're part of the audience and the band. The sound recording is excellent, and Corey's famous caustic voice never sounded better. In fact, some of his vocals are astonishing. For the uninitiated, there is more than enough colourful language, although if you are a big Slipknot fan this is unlikely to worry you now. Throughout the performance there are mini-segments showing the band assemble the stage, warm up, sound-check, get dressed, put on make-up and more. The second disc contains other interesting features, including some videos and a feature that allows you to access hidden segments within the show. Personally, this is my favourite music DVD by a very long way and I've watched it many times now. Nothing beats it for an hour or two of adrenaline filled metal mayhem with great theatrics. No big Slipknot fan should be without.
