I was there in a semi-professional capacity. AT&T Labs had developed a multi-channel 3D microphone array and we hung it above the emerging artists' stage. I didn't stay overnight at the facility, so I only saw the degradation when I arrived in the morning. The second day we came in, all the commercial tents were soaked with urine and every trash can had been dumped out and piled up to form a massive all-day drum circle. We left before things got really bad, but it was obvious they were headed in an ugly direction (largely, I think, due to deliberate neglect and extractive behavior.)

On the bright side: the scientists at the Labs were very pleased with the microphone's performance, since (sitting in a room with six speakers) you could clearly hear the drum circle behind and outside the stage doors.
