I went to a Prodigy concert.
I would say that aside from the hard core punks up the front, I was the oldest person in the mosh pit by about 10-12 years.
I was really into kickboxing back then, and had my hair cut very short. A 6'2" and 200lbs of skin head kickboxer doesn't get too many skinny 15 year old punk wannabees offering to lift him up and let him crowd surf.
Good concert otherwise, even if Maxim was off his tree on drugs.
