Harmonia

Harmonia was a West German musical "supergroup" formed in 1973 as a collaboration between members of two prominent krautrock bands: Cluster's Hans-Joachim Roedelius and Dieter Moebius joined by Neu! guitarist Michael Rother. Living and recording in the rural village of Forst, the trio released two albums—Musik von Harmonia (1974) and Deluxe (1975)—to limited sales before dissolving in 1976. AllMusic described the group as "one of the most legendary in the entire krautrock/kosmische scene."

In 1997, a series of shelved 1976 collaborations between Harmonia and British musician Brian Eno saw release as Tracks and Traces; it was reissued with more unearthed material in 2009. Following the release of the live album Live 1974 (2007), the trio reformed between 2007 and 2009. In 2015, Grönland Records released the 6-disc box set Complete Works, featuring remastered recordings and archival material.
