 This concert was recorded on the fly with no sound or video checks  of any kind. Reportedly, the crew had a hard time driving from São  Paulo to Rio de Janeiro, and by the time they arrived it was after  noon, when they wouldve otherwise been close to done setting up. By  the time they did get finished setting up, the crowd was gathering  at the door, and there was no holding them back, so they were  literally forced to go without a sound or video check.
