Rother is a multi-instrumentalist (primarily guitar and keyboards) who, along with a catalog of several solo albums starting in 1977, is best known for having co-founded the German group Neu! with drummer Klaus Dinger (five albums between 1971 and 1996), and his collaborative efforts with Hans-Joachim Roedelius and Dieter Moebius (aka Cluster) under the name Harmonia (two albums, one in 1974 and 1975, with later 1976 sessions recorded with Brian Eno; the studio tapes for the latter disappeared but were found by Roedelius two decades later; he remixed the tapes and released the results as "Tracks and Traces" in 1997; Rother was the main producer for the version re-released in 2009).
