Can were a German experimental rock band formed in Cologne in 1968 by Holger Czukay, Irmin Schmidt (keyboards), Michael Karoli (guitar), and Jaki Liebezeit (drums). They featured several vocalists, including the American Malcolm Mooney (1968–70) and the Japanese Damo Suzuki (1970–73). They have been hailed as pioneers of the German krautrock scene.

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.
