I listen to KMFDM and have seen them in concert. It is a genre of music commonly known as industrial music that combines synths, big beats, and guitars, and it happens to be my favorite type of music. KMFDM were unfortunately cited by the Columbine shooters too and took a hard stand against their actions back in 1999. They would not support what happened in this case either. I met Sascha at their show and he was calm, cool, friendly, and down to earth. One of their famous songs is “A Drug Against War,” in which they describe their own music as being just that. They do not support this kind of violence. It is often an angry, abrasive type of music that can attract the down and out though.
Let’s not judge (and not saying you personally are) based on the type of music she listened to, as I have listened to this style of music since high school and have never hurt anyone. I happen to be a high school teacher of 27 years and lead vocalist, keyboard player, and songwriter for two industrial bands over the years myself! While industrial music is a counterculture movement that can draw some interesting types of people, I love the energy of the music.
