The original question was “What constitutes a live performance?”

I think I have to say that once you add any backing tracks, it ceases to be a live performance in the truest sense. But it’s still not karaoke by any stretch of the imagination. Especially for those who create their own backing tracks using BIAB or other means vs buying them. It’s an art form incorporating “live” instruments and/ or singing and computer skills to create the finished product.

But it ain’t “live”. JMHO.

P.S. Eddie. I'm not a Van Halen fan either. Too many (useless) notes in too little time.
