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. 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. AllMusic described the group as "one of the most legendary in the entire krautrock/kosmische scene." Collaborator Brian Eno described them in the mid-1970s as "the world's most important rock group." Harmonia's work would influence the development of ambient music by Eno and albums by David Bowie, as well as other electronic and rock acts. History Formation: 1973-1975 In 1971, the duo of Moebius and Roedelius, members of Cluster, moved to the rural West German village of Forst near the Weser River after being offered residence in several centuries-old farmhouses by an antiquarian who hoped to establish an artist's commune there. Michael Rother put his project Neu! on hold in early 1973 to meet with Roedelius and Moebius, hoping they might act as a backing band for live Neu! performances. Upon jamming with the duo, Rother claimed that "it was sort of a musical love at first sight, really [...] it was just something I hadn’t experienced before. In good moments, the three of us could produce a real, live music." Together the trio recorded in their own home studio in Forst, and chose the name Harmonia partially as a joking reference to the common German phrase for "choir." The idyllic, natural surroundings would influence their work. They recorded two albums under the name Harmonia: Musik von Harmonia in 1974 and Deluxe in 1975, both released on Brain Records. The former was produced by Harmonia themselves using a primitive mixer and three tape recorders. After its release and a period on tour, Rother took a short break from Harmonia to record the third Neu! album with Klaus Dinger, Neu! '75 (1975) in order to complete his contractual obligations. In
