Karl Bartos (born 31 May 1952, Berchtesgaden, Germany) was, between 1975 and 1990, along with Wolfgang Flür, an electronic percussionist in the electronic-music group Kraftwerk. He was originally recruited to play on its US "Autobahn" tour. In addition to his percussion playing, Bartos was credited with songwriting on the Man-Machine, Computer World, and Electric Café albums and sang one lead vocal on the latter.
He left the group in 1990, reportedly frustrated at the slow progress in the group's activities because of the increasingly perfectionist attitude of founding members Ralf Hütter and Florian Schneider.
In 1992 Bartos founded Elektric Music. This new project released the Kraftwerk-style Esperanto in 1993, and then the more guitar-based Electric Music in 1998.
