Highly influenced by artists like Salvador Dal?, Tangerine Dream began life as a kind of surrealism in music. After having sold off all of their "traditional" music equipment, the Berlin-based band began using strictly electronic devices like synthesizers, sequencers, mellotron, moog and other self-built toys. These rare recordings trace the band from this initial experimental period (1972), through to it's commercial success with Virgin later on in the decade.
