Good points Donny but I'm not sure why you say that an arranger keyboard won't cut it. I know a OMB arranger keyboard guy is exactly the standard at most events that use live music but I don't see why a good looking guy or girl with killer keyboard chops, an exceptional singing voice, and a great stage presence couldn't do well. If you are great at what you do, I don't think it matters if you got a full band, sing to backing tracks or whatever. Use the method that works best for you
