I used to be ambivalent about Rammstein until I saw them live at X-Fest. They put on a hell of a show.
You have to give a guy some points for coming out onto stage while ON FIRE. He also had 3 pedals on stage. 1) shot fire up in the air 2) shot fire out over the crowd 3) shot water out at the crowd. He would use the pedals to alternately scare and sooth the audience. The mosh pit during this madness was dangerously violent; I saw two people get taken out on stretchers. All that was BEFORE Fred Durst came out and incited the crowd to basically riot (for which he later got arrested.)
