Sound system was way too loud. My hearing was not back to normal until 2 days after the show. Absolutely terrible sound quality. It was so loud the music was distorted and did not sound like the same songs when played on the radio. I could not understand the spoken words of the musicians in between songs because the sound was so badly distorted. Had no idea what they were saying. The police presence was not nearly adequate for the crowd. I was stuck on the 280 freeway exit for at least half an hour, hardly moving an inch per every 5 minutes, and it was the same traffic jam situation all the way to the parking garage. Therefore, I missed the artist I wanted to see the most, Taio Cruz, as he apparently was the first one on the show at 7:30. So mad! Heard all the others who were not the ones I wanted to see as much. While waiting in my car, heard on 99.7 FM that I could have stayed home and watched the whole show on my computer. Why did they not say this earlier? I would have stayed home, saved my money and my eardrums, and would have gotten to see the one person I really wanted to see perform. So it was a total waste of time and money. Turn down the sound, please. You are going to make all the young people deaf with the sound turned up that high. Forgot to bring my earplugs. Should have known better. Terrible. The musicians were actually pretty good, but I could not appreciate them because of the noise level. It did not do any good to clap, as no one could hear the applause over the huge racket.
