Ah Dj's... probably one of the things I'd start doing again right away if I had the chance.
Kid Koala is unique. I respect him mostly for his talent, because the music-style he choses to work with ain't easy at all. Very original.
Tiesto...
Yeah he's ok at mixing, but mixing 2-3 venyls at once once you got your 135 BMP equal is kinda easy going after that and the crowd who's usually flipping, half of them are truely flipping on techno/trance parties (drugsssss)
About DMC's. I can't find that old clip on Google anymore, it's from 1997 but it's close to this one from another Japanese guy.
