There's something intangible about dancing to a live band that can't compete with DJ'ed music. Of course the band must be good, but when it's good it's REALLY good, and I don't get that feeling from a DJ'd dance. When a good band comes into town I'll definitely spread the word.
I'm marrying a jazz musician, so I certainly hope dancers will continue to be willing to pay to dance to live music. Otherwise, I'll become one of those vagabond Lindy Hoppers this thread keeps talking about.
This year I took the next step and went from dancer/DJ to performer. I'm singing in a band called the Atomic Rhythm All Stars (insert shameless self-promotion here), which I sort of fell into because of my boy, who plays in the band, and because I was in the right place at the right time when another vocalist's audition went awry. Being a part of a band absolutely means that I promote live music, as well as DJ'd music, so either way I have an amazingly fun job for the dance.
Being able to share these recordings from the past, as well as recreate this music from the past and share it with others...it's like being on both sides of the fence, no?
True, right now the DJ gigs outnumber the band gigs, but I don't know if that will change. If it does, it will probably be a result of band gigs for non-dancers, while my DJ gigs would remain for dancers.
