 Rother, who unlike Dinger was interested in the Krautrock scene contemporary with Neu!, had been impressed by the track ""Im Süden"" from Cluster's second album "Cluster II".He at first envisaged a Neu!–Cluster super-group, containing Dinger, Moebius, Roedelius and himself.After an initial jam between Moebius, Roedelius and Rother at Forst (captured in the track ""Ohrwurm"" on Harmonia's debut) Rother decided to stay at Forst and prepare a new album with Moebius and Roedelius as Harmonia, essentially abandoning his work with Dinger.
