My favorite albums of the entire Eno/German collision were the two he made with Cluster, which have oddly different titles, possibly because of how Cluster felt about being Cluster. This one finds Moebius and Roedelius calling themselves Cluster, and Eno reducing each track to a clearly heard collection of elements. Foregrounding everything is his skill and, on this album, we really hear the energized middle space where Cluster lives. There’s some very welcome bass guitar and a higher class of engineering here. The result is a perfect high summer record: woozy and full of dense colored liquid.
