i don't want to hear 8 hours of the same type of music, no matter what it is, so for the most part, i'm all for having different styles represented through the night.

i did have a terrible outing one time though due to lack of planning by the promoter. i was booked to play techno at prime time, but all the other dj's booked were local hard house dj's, and they were all competing with each other to be the hardest and fastest. so there was 4 hours of hard house, then me playing techno for an hour, then 3 more hours of hard house. nobody in the croud liked techno. i ended up playing acid techno pitched up to +8 and the dancefloor looked bored out of their minds the whole time.

i'm not trying to dis hard house specifically. it's just that when dj's play off each other too much, they all get in "the zone" and then anybody who plays anything different sounds "off". i've seen it happen with deep house, drum & bass, etc, etc.
