Karl Bartos (born 31 May 1952 in Berchtesgaden, Germany) is a German musician and composer.
He was a drummer of college band The Jokers (later The Jolly Jokers in 1975 ) as Carlos Bartos, around 1965 to 1972. Between 1975 and 1991, he was, along with Wolfgang Flür, an electronic percussionist in the electronic music band Kraftwerk. He was originally recruited to play on Kraftwerk's 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.
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. In between the two albums, Bartos collaborated with Bernard Sumner and Johnny Marr on Electronic's 1996 album Raise the Pressure, and co-wrote material with Andy McCluskey of OMD, which appeared on both Esperanto and OMD's Universal album. In 1998, he also produced an album by Swedish synthpop band the Mobile Homes, much in the style of his work with Electronic: guitar-pop with very slight synthetic references. It was received as a great disappointment to synthpop fans, but it sold more than any of their previous albums and was used in an advert for an airline.
