Einheit and also known as Mufti, (born 18 December 1958, in Dortmund) is an industrial and electronic musician and actor from Germany.
Most of the percussions which FM Einheit played on were custom-made metal instruments or such tools as a hammer drill.
Live performances of Einstürzende Neubauten with FM Einheit included much metal banging, destruction on the stage and even fire.
He played the lead role in the 1984 feature film Klaus Maeck's Decoder, a cyberpunk critique of muzak.
FM Einheit left Einstürzende Neubauten in the mid-1990s during work on the album Ende Neu, due to a lack of creative interest.
