Krautrock is a broad genre of experimental rock that developed in West Germany in the late 1960s and early 1970s. It originated among artists who blended elements of psychedelic rock, avant-garde composition, and electronic music, among other eclectic sources. Common elements included hypnotic rhythms, extended improvisation, musique concrète techniques, and early synthesizers, while the music generally moved away from the rhythm & blues roots and song structure found in traditional Anglo-American rock music. Prominent groups associated with the krautrock label included Neu!, Can, Faust, Tangerine Dream, Kraftwerk, Cluster, Ash Ra Tempel, Popol Vuh, Amon Düül II and Harmonia.

Experimental rock, also called avant-rock, is a subgenre of rock music that pushes the boundaries of common composition and performance technique or which experiments with the basic elements of the genre. Artists aim to liberate and innovate, with some of the genre's distinguishing characteristics being improvisational performances, avant-garde influences, odd instrumentation, opaque lyrics, unorthodox structures and rhythms, and an underlying rejection of commercial aspirations.
