If Phaedra was the discovery, Rubycon (1975) is the consolidation, two side-long movements that drive the sequencer-and-Mellotron method to its most sustained and assured. Tangerine Dream had by now perfected the slow build, patterns layering and mutating across twenty minutes until you lose track of where a phrase began.
Many hold it as the high-water mark of the band's Virgin period, the point where technique and atmosphere lock together. Less an album of pieces than a single immersive room you step inside.
