Why is it so easy to tell the difference between live and recorded music?


I would direct you to Steve Guttenberg’s most recent YouTube video. It is a question that I’ve often asked myself. Any thoughts?

In spite of my dog, I still prefer listening to my system than listening to almost any live event, (the exception being the symphony).

I was told a dachshund can bring down a 160 lb man who’s had a twenty foot head start.
Mostly because your brain is telling you there's no way it could be live music when the eyes transmit to it an image of speakers. Place musicians on a stage pretending to play while a pair of speakers behind them actually play, then it gets more difficult to tell the difference.
