KMFDM (originally Kein Mehrheit Für Die Mitleid, loosely translated as "no pity for the majority") The German-American Project/Band and also the Foundation Stone of Industrial music and Culture, as we know it! Not only the music but also the official videos of KMFDM (and the album covers) are works of Industrial Art.
There are too many albums and singles of KMFDM (and associated projects) out there. "Our" Kapt'n and leader Sasha Konietzko is the most productive industrial artist. "Productive" and "Inspired" are the 2 key-words of the "experimental lab" they made.
Listen to the Heavy Metal Industry, called KMFDM check out those videos and buy the albums. If you are not familiar with "Symbols", Adios", "Nihil", "Naïve", "Angst", "Attack" "Uaioe" and many more, you are not familiar with the roots of industrial music.
Enjoy a fine piece of machinery that works "Better than the Best & Harder than the Rest", since the early 80's: Money (official video)
