Aside from the ravesignal stuff - Sonic Solution (Music, Quest, Beat Time, On the Move, Turbulence, Baghdad)
The entire '4th Sign' album - absolute class
Even some of his later stuff still sounds great to me, the Starship enterprise EP and Electronic Highway album... Only thing I remember not liking by him was the album he did around '97 which sounded like he was trying to copy what the prodigy were doing at the time (the one with that awful sugar daddy tune on)
Was a pretty good dj as well, he did a radio 1 essential mix in 1994 which I taped off the radio at the time and still love today
