Harald Grosskopf first appeared early in the timeline as the drummer for Wallenstein, playing on their first four albums. He then performed with Klaus Schulze off and on in the mid-70s, before joining forces with Manuel Göttsching and Lüül Ulbrich in Ashra in 1978. Grosskopf got the opportunity from Sky Records to record his first solo album, Synthesist, in 1980. With only a Mini-Moog, sequencer and a somewhat legendary eight-track tape machine, he retreated to the Krefeld home of Udo Hanten (one half of the soon-to-be electronic group, You).

Another musician who cut his teeth in Berlin's Zodiak Free Arts Lab in the late 60s, guitarist Günter Schickert was a fixture in the city during the 1970s. Armed with a Dynacord Echo machine, he was also a pioneer of echo guitar, in the vein of his contemporary Achim Reichel. In 1974, he recorded his first album, Samtvogel ("Velvet Bird"). Although initially a private pressing, it was picked up and reissued by the Brain label in 1976.
