Oliver Lieb is probably my alltime favourite trance producer, he's made hundreds of tracks, and 99% of them are quality. I've only been into trance since atound 2000, but I've spent most of the last year or so searching out old releases from the nineties, as they're simply much better then what's released today. Most of the old releases are difficult to get hold of though.
At least I've been able to get my hands at all the L.S.G. albums, and they are some of the highest rated cds in my collection.
