Thanks for the comments guys, I really appreciate it.
Khar,
Essentially all that's going on is just crossfades and drops. Tracks overlay each other for sections, but I haven't jumped back and forth between tracks in this mix. I'm not trying any crazy Mixmaster Mike stuff with multiple tracks going at once.

The idea is that this is the kind of thing you could play in a club and people could dance too - interesting and relatively quick-changing, but not so rapid that you can't find a groove and stay in it for a few minutes.
Some of the mixes are relatively quick, some are quite a lot slower. Nuisance is pretty much spot on with the first couple of fades - mostly, what I've done is start the incoming track playing on my monitors, synced the beats and tempo up, and faded in in between phrases. Most dance tracks (breaks and DnB can be fiddlier) have some kind of a breakdown after four or eight or twelve phrases, so once you get the hang of it, it's easy to time it so that tracks overlay for maybe sixty-four bars giving a nice polyphonic overload, you can slap totally out of the old track into the breakdown for a few bars, hopefully followed by a drop that puts the dancefloor on rinse cycle.
The switch between Feel Good Inc. and Electric Disco is a good example of this. Around about 14:45, FGI starts calming down a little, and I'm syncing ED going on my monitors. At 15:20, ED is faded up to about 40%. It takes a little tweaking to get the beats lined up, I slowly bring it up to about 75%, only ever fading up in between phrases. At 16:04, I pretty much just ramp the crossfader across, the breakdown happens, people on the dancefloor take a breath. At 16:34, the drop comes along and people theoretically go nuts. Not very complicated, but it's surprisingly hard to do on the fly.
The hardest mixes on there were getting into and out of Bucky Done Gun.
EDIT: Guys I am intrigued by these industrial sets. I sorta started getting into industrial when I was 18 or so, but then I got sidetracked by hip-hop and more general electronica. I might have to look into it again.
