Since my friend started to play at 7 in the morning

Are there people that stay there all night to party? That seems like the old school sort of "rave" sort of atmosphere, which would have been my only exposure to something like this. At one of them I left the club at what was now a Sunday morning and there were people going down the street carrying on with their day, some of them on their way to church and it kind of made me feel like a gooner being so wasted as the birds were chirping and what not.

The sound engineering is so important. I went to a show in Bangkok many years ago and I don't think they put any thought into the sound because everything was just super loud. This was the only time in my life that my face hurt and I could feel the pain running down from my ears down the side of my neck from the force of the sound that I had endured for something like 6 hours at that point. I bring ear protection to shows now to protect what hearing I have left.
