KMFDM is a band that makes music. They put together lots of different sounds like guitar, drums, and bass to create their songs. These songs are often loud and fast and have lyrics that talk about things like politics, society, and personal feelings.
KMFDM started making music a long time ago, back in 1984. They are from Germany, but they sing in both German and English. Their name stands for "Kein Mehrheit Für Die Mitleid" which is German for "No Pity for the Majority".
Some people really like KMFDM's music and think it is very cool, while others don't like it so much. But whichever way you feel about KMFDM, they are definitely a unique and interesting band to listen to!
