Krautrock is a broad genre of experimental rock that developed in Germany in the late 1960s. The term was originated by English-speaking music journalists as a humorous name for a diverse range of German bands whose music drew from sources such as psychedelic rock, avant-garde electronic music, funk, minimalism, jazz improvisation, and world music styles. Largely divorced from the traditional blues and rock and roll influences of British and American rock music up to that time, the period contributed to the evolution of electronic music and ambient music as well as the birth of post-punk, alternative rock and new-age music.
