This 1974 masterpiece from Christopher Franke, Edgar Froese, and Peter Baumann ebbs and flows with richly dark soundscapes of electronic sounds and synth. Phaedra was a progenitor for much ambient--and some dance--music, influencing such artists as Steve Roach. After listening to Phaedra it's easy to understand why. The signature pulsing of thick, beautiful Tangerine Dream synth falls across the ambient treasures here, pulling along the orchestral dreamscape before oozing aside for thick washes of expansive sound. The now-classic title cut is both soothing and ghostly, throbbing with subtle sequences and twisted metallic calls before diving into a swamp of nightmarish whistles and hoots. "Mysterious Semblance" soars and swoops like a lovely electronic eagle, bringing tripped-out light and cosmic dignity to the collection. This and the follow-up Rubycon are juicy pieces to the Tangerine Dream pie. --Karen Karleski
