I'm sure this man needs no introduction, but on the off chance you don't know who he is, it's Ice-T and his band Body Count. The music is a curious mixture of Thrash and Rap, but mostly Thrash. He was very good at talking to the crowd (something a number of bands I've shot could stand to learn) and got them laughing as well.
His enthusiasm for the concert meant he was bouncing all over the place and coupled with a packed press pit, made good shots difficult to get.
I threw in the drummer pic because I liked his mask.
