It ain't gonna happen and it's beside the point. Like the Irish superstars, he's a great showman who soaks up the past. What a dialogue and d tente that would have been. The genre's tantric ideal is the long set sustained at the brink of climax. DJs like John Digweed deliberately select characterless tracks rather than orgasmic anthems, because they work better as mixscape components.
Progressive tends to be a rather level, peakless experience mild and middling.
It's certainly the last genre I thought would generate anything exciting, until a chubby-cheeked German called Timo Maas came along. Sound becomes spectacular. Still, a curious blankness lingers. Eliminating the aspects of rave that harked back to youth movements like hippie and punk, progressive achieves a kind of purity. Sound becomes spectacle.
