CLUSTER is a duo formed by Dieter Moebius and Hans-Joachim Roedelius. They were one of the best krautrock ensembles ever, in my humble opinion, and together they created a sound incredibly mellow.
In this 1976 album -my favourite one, by the way- they use very child-like and minimalist melodies, made up of keyboard progressions and electronic effects (if you have appreciated LULLATONE you will probably also like the last song in here, a very musical-box-like, "In ewigkeit", a slow and tender lullaby).
It is also not avaible anymore (on Amazon a used copy is on sale at 49,50 $ !), so take advantage of this!
