There are at least three groups called "Monoton" One is an Austrian experimental minimal electronic project started by Konrad BECKER in 1979. In 1998 The Wire magazine singled out Monoton’s record "Monotonprodukt07" from 1982 among the 100 most important records of the 20th century. In 1992 the Dutch techno DJ Daniël Leeflang (a.k.a. DJ Dano) became an additional member of the project. The other is a quartet from Copenhagen, Denmark. They've been around since '96.
