Nakedness aside, are you familar with LCD Soundsystem? Because when they play live, they do something an awful lot like what you're describing. I think there are click tracks or loops in there, but there's a live drummer guy playing over them. And several keyboard players.

Using old keyboards with live musicians is very "hip" right now. And when the songs being played are worth it, it's awesome. But hauling out a junky DX7 and claiming that your musical turds are more authentic than someone else's awesome song that just happens to use a sequencer, is wack.
