Norman Granz´s Jazz at the Philharmonic was a way to gather some wonderful musicians of that era, a neverending all-stars jam session. They produced marvellous music (Hawk-Prez-Illinois Jacquet; Bird&Prez...).
It was a musical, sociological, and cultural phenomenon whose most outstanding element, often, was audience participation.
Nevertheless, the audience's contribution usually consisted not only of listening, but of whistling, yelling, stomping, and clapping time on the wrong beats.
It was criticized, as well, of being some kind of slight disorganization and an all-out blowing.
