We stopped at a County Fair last weekend while travelling through Arizona. They had a 7 or 8 person "group" singing on stage. Good vocals (mostly) and definitely what you would call a "live" performance, despite not having a single instrument in sight.

I let the word "karaoke" slip out while discussing them with the wife. Her quick reply was, "it's not any different than using Band In A Box" and of course she was right.

So if a group of singers constitutes a "live performance" then I would say that ANY live singer constitues a live performance. If that is the case (and not everyone here agrees that it is), then BIAB or backing tracks only ADDS to the performance, at least in my estimation.

My feeling is, if there's a "live" person performing, either a capella, with a guitar, with a piano, with a band or with BIAB/backing tracks, it is a "live performance".

The only question now becomes "what about lip syncing"????

Just my 2 pesos worth <grin>
