Later labeled as one of the first krautrock groups, they transcended mainstream influences and incorporated strong minimalist and world music elements into their often psychedelic music. Can constructed their music largely through collective spontaneous composition –– which the band differentiated from improvisation in the jazz sense –– sampling themselves in the studio and editing down the results; bassist/chief engineer Holger Czukay referred to Can's live and studio performances as "instant compositions".They had occasional commercial success, with singles such as "Spoon" and "I Want More" reaching national singles charts. Through albums such as Monster Movie (1969), Tago Mago (1971), Ege Bamyasi (1972) and Future Days (1973), the band exerted a considerable influence on avant-garde, experimental, underground, ambient, punk, post-punk, new wave and electronic music.
