I was a bouncer at The Rialto in Tucson for a show that they supported on. I don't remember what show it was (Kittie, Shadows Fall, Static X, Soulfly, Hatebreed or any other number of shows I worked), but I just remember how they combined speed and aggression with melody, harmony and emotion and they do it so seemlessly. This was about 2 years ago and I haven't looked back yet....
