Hans-Joachim Roedelius and Dieter Moebius parted ways with Conrad Schnitzler to form Cluster in 1971. Their improvised music proved ground breaking in terms of structure and timbre, mostly composed by treated instruments and electronic means. After leaving Berlin, they settled in Forst, Lower Saxony, and built a home studio, which fostered collaborations with many musicians, including Michael Rother, Conny Plank. Brian Eno and Mani Neumeier.
German for "fist", Faust were pioneers in the studio. After two albums for Polydor, they signed with the fledgling Virgin label. Priced as a single, The Faust Tapes album sold a staggering 50,000 + copies - amazing since it is one amazingly weird pastiche. Their live appearances were explosive (literally), as the pinball machines and jack-hammer legends detail. The band carried on for nearly two years after IV, however that album, recorded outside the Wumme studio, was their last.
If Cream or Jimi Hendrix invented the "power trio", Germany's Guru Guru defined it on acid, offering the purest psychedlic freakouts on their early albums. Later albums, ever under the direction of Mani Neumeier, traversed all sorts of diverse music.
A collaboration between Michael Rother of Neu!, and Hans-Joachim Roedelius and Dieter Moebius of Cluster, Harmonia released two albums for the Brain label, and a third collaboration with Brian Eno (a precursor to Cluster & Eno) was released decades later.
