1970 he had a 56 channel mixing desk hand built by himself Peter Lang and Michael Zähl. and went on to produce and/or engineered many recordings by significant German progressive/experimental music acts often referred to as krautrock internationally, including Kraftwerk, Organisation, Neu!, Cluster, Harmonia, Night Sun, Holger Czukay and Guru Guru. In 1977, through Brian Eno, Plank recruited Dave Hutchins from Island Studios, as house engineer. Hutchins undertook recording and mixing roles on many of the productions originating from the studios in the following ten years. As a musician, Plank played guitar and keyboards on three Guru Guru albums: Kang Guru, Guru Guru, and Mani und Seine Freunde, the Os Mundi album 43 Minuten, and Cluster's self-titled debut album. In 1978 and 1979 he added guitar and percussion to two Roedelius solo albums, Durch Die Wüste and Selbstportrait. He was a member of the short lived band Liliental, contributing guitar, keyboards, and vocals. In 1979 he went into the studio with Dieter Moebius to record the first Moebius & Plank album, Rastakraut Pasta which was released the following year. 1980s Plank continued to work as one half of the duo Moebius & Plank, recording four additional albums. Their second album, Material, was released in 1981. Their third album, the African-influenced Zero Set, with Guru Guru drummer Mani Neumeier, was released in 1983. These two albums are early examples of the predecessors of techno and electronica. In 1983, Moebius & Plank also recorded the album Ludwig's Law using an Emulator, an early form of sampling keyboard that enabled them to duplicate other instruments without having musicians to play them. Mayo Thompson of Red Krayola contributed vocals, mainly spoken monologues. The project was rejected by Sky Records and was not released until 1998. The final Moebius & Plank collaboration, En Route was recorded in Conny's Studio in 1986 but left incomplete as Plank's health deteriorated. It was completed and mixed in 1995, primarily by Dieter Moebius, and released that year. During the eighties, Plank remained in high demand with the new generation of electronic pop and new wave artists, including Devo, the Meteors from the Netherlands (Hunger in 1980) and (Stormy Seas in 1981), the Fred Banana Combo, Ultravox (Systems of Romance, Vienna and Rage in Eden), Echo & the Bunnymen, Freur, Killing Joke, the Tourists (Luminous Basement) and Eurythmics (In the Garden).
