About Hans-Joachim Roedelius

He is notable for his prolific discography, either as a solo artist, as part of a band, or in collaboration with other artists. He has more than 100 releases to his name. He also performed in the ambient jazz trio Aquarello, and released several solo studio albums. In 1968 Roedelius co-founded the music commune known as "Human Being" and co-formed Zodiak Free Arts Lab, the center of Berlin's Underground Culture at the time, with conceptual artist Conrad Schnitzler. Rother left Harmonia to pursue his solo career and Cluster returned to the studio to record Sowiesoso which was released on Sky Records. The first of the lengthy Selbstportrait series was released in 1979, being material done beside his work with Cluster and Harmonia, without the input of his collaborators.
