I think musicians helped to screw themselves by not playing the hits that the dancers wanted. Look at the scenario:
(SOME) Bands were offering poor imitations of the songs, taking breaks ( and going in the parking lots with their chicks, and/or booze etc..

)
Couple that with increaced liablity insurance to the club owner, and DJs started to look attractive. Less room, less $$$ less hassle - we screwed ourselves, collectively speaking.
Personally - I never drink at work, and when I'm off stage, I'm with the crowd ( always on duty ) and I play a pre programed mix that I pick after each set to "pace" the room while I'm off.
If more bands acted like a part of the room, instead of Prima Donna's - there would be more live music. The drinking/driving laws were the largest catalyst to twart the entertainment business, and while I applaude the laws and the cause .... I feel the effects of the reduced "fun factor" in the clubs and parties.
I'd love to see more people go out and have fun in a more moderate way. I have NO tolerace for drunks or show offs, and the music and food should be PLENTY to celebrate on any given night.
I predict this thread to "explode" with comments anytime now ! It's a touchy issue for many.
