The Julian Liberator one (I think its no 23) is the best mix I have ever heard full stop
Used to chuck it on after every party
90 minutes of pure techno filth, really raw and dirty - there is only one point where it starts to drift out at about 70 minutes and you really have to strain to hear it but he pulls it back together. Impeccable mix and track selection.
Try and track it down, I have the tape but no tape player any more
