Hey you DJs:
If you want to be a real performer, ditch the vinyl and learn to make music the old fashioned way, with a musical instrument.
I've read the rest of the thread, but I wanted to go back to this, because you're painting a broad brush here. I know lots of DJs who play instruments. I played violin for 4 years, and keyboards and sang in cover bands. It was boring. I found no creative expression in playing the same songs over and over.
When I discovered djing, it was an open book as far as creative expression. I started in the late 80s when you only had 2 sometimes three turntables, a mixer, effects and a maybe a tape deck. I incorporated many styles of music into my sets, Pierre Henry was one of my favorites, along with classical pieces, jazz, soul,latin, classic rock and african. Not by just playing a song but layering sections of them with more contemporary music. And at the same time manipulating EQ, and effects, all on the fly. This is not easy. It takes a lot of hard work to master, much like an instrument. Learning how to read a crowd is extremely important. When all these things come together, it the most amazing experience for both the DJ and the crowd.
I, also, often had drummers, guitar players, percussionists, flutists, and even saxophone players come down and jam with me.
I don't know what you mean by xxx-hop, but, yeah club music loses it's point when it's not being manipulated and layered, which is it's true intention. it's a foundation for open-ended creative expression, and can be morphed into whatever a DJ feels would move their audience.
I'm retired now and love to go out and WATCH a live band, but if I want to dance, I'll go HEAR my favorite DJ.
