Q:  9.4.19  2:05 am really? i guess i'm naive cuz i thought usually when you are watching a professional live concert recording you are hearing what actually happened at the concert. i don't doubt that some people re-record certain bits but everyone?
A: pretty much. also they tune up the vocals. the results are usually fantastic. until you realize the changes that have been made, and then it's still fantastic but it may give you a strange feeling deep inside
