It's a view held by many that Nick Warren 'is' GU. And it's not a wholly unfounded view, either, given the Boxed boys have called him more than anyone else to get on the decks. His offerings have been consistently superb, GU24 (intended originally as NW's last GU, a decision divinely reversed later for Shanghai) bears little resemblence to his former offerings, nor those of any other DJ. Which was rather brave at the conception stage.
Warren here goes back to his Massive Attack DJ roots since this album is far more about unhurried depth of sound and trip-hop than it is house. The inclination to fill dance floors is only occasionally visited, and is instead flanked by a more constant presence way down at the bottom of the BPM scale. It's a lesson in track selection and mixing, and its structure is one of human-like mood changes that one could easily experience when immersed in such music or a related club night.
So it's all the more confusing that all the tracks seem natural in their progression, given that the structure is mood-like not directional. There are precious few mix albums like this where you can see each track belongs - forget fillers. So it would do injustice to those I don't mention if I were to pick out highlights (although the fact that there's a Planet Funk song should accelerate your dive to the 'buy now' button). The songs fit, the mixing is, well, Nick Warren, and it shows that the slowing and broadening of prog house only makes it more deserving of its 'intelligent' tag.
