From the very beginngin to the very end, Donny. It's all about the entertainer and what he or she is prepared to do and how well they perform. From watching this from end to end, it has very little to do with whether the person behind that table is a keyboard player or a DJ. And, I suspect with the aid of some foot pedals they could easily handle the light show as well. It would just be a matter of preparation.
Just my .02 cents worth,
Gary
