Hans Joachim is a pioneer in the field of the exploitation of electrically generated tones, sounds and noises, and belongs to the founders of contemporary popular electronic music. His discography lists about 80 releases, and there are more than 10 productions ready to be released in the future.

Roedelius was born October 26th, 1934 in Friedenau/Berlin and has been living in Baden, south of Vienna, since 1978. He started as a professional composer/musician/texter in the late sixties, with sound-experiments described as a sort of "anarchic musical actionism".

He has worked with choreographer Caroline Carlsen for the "Theatro e Danza la Fenice" in Venice, with Esther Linley, Mark Lintern-Harris and Joao de Bruco for the "Wiener Festwochen", the "Donaufestival", the "Eurokaz" in Zagreb, the "Szene Salzburg" and other Festivals.

He was a founding member of groups such as:
"Geräusche", "Plus/minus", "Per Sonare", the free artslab "Zodiak" in Berlin, "Kluster", "Cluster", "Harmonia", "Meeting Point Vienna", "Friendly Game", "Aquarello" and "Tempus Transit".

He has collaborated with many composers and musicians such as:
Brian Eno, Holger Czukay, Michael Rother, Konrad Plank, Peter Baumann, Dieter Moebius, Fabio Capanni, Jurij Novoselic, Hiroshi Kobayashi, Andres Gil, Felix Jay, Nicola Alesini, Konrad Schnitzler, Alexander Czjzek, Eric Spitzer-Marlyn and many others.

In 2011, Roedelius and Dieter Moebius broke-off formal ties with one another and Cluster. Roedelius went on to form a new variant of Cluster called Qluster. The new lineup consists of Hans Joachim Roedelius and Onnen Bock.
