it really all depends for me

i like to program my sets based on what style the dj before me is playing, and the dj after me is playing, because good flow is not just about your set, it is about the entire night...

but sometimes it really doesnt matter, cause if the dj is playing crap before me i will start out with what ever i want, and it tends to be that i start off --

funky, like varela, sims, ignition tech, shufflemaster primate style stuff
get harder with some pounding grooves, henrik b, beyer
then harder with some glenn wilson, lars klien, dave the drummer, anxious, and maybe some acid techno
then harder techno like asem shama, london techno stuff, speedy j, chris liebing
and then i either end it off with acid techno or end it off mellow depending on the style of dj after me

i really try to play as many styles of techno as i can in a set
