The high points of a show can\'t be revealed to others if there\'s no recording.
I like to go over a recording of a show and see and hear all that went on.
Then it could be shared with those not there and also have promotion material for the band.
A band can then go over what they sound like and take it further to what they want.
I also feel a band\'s performance is owned by the band, not the venue they played at.
