Phaedra is one of the most important, artistic, and exciting works in the history of electronic music, a brilliant and compelling summation of Tangerine Dream's early avant-space direction balanced with the synthesizer/sequencer technology just beginning to gain a foothold in nonacademic circles. The result is best heard on the 15-minute title track, unparalleled before or since for its depth of sound and vision. Given focus by the arpeggiated trance that drifts in and out of the mix, the track progresses through several passages including a few surprisingly melodic keyboard lines and an assortment of eerie Moog and Mellotron effects, gaseous explosions, and windy sirens. Despite the impending chaos, the track sounds more like a carefully composed classical work than an unrestrained piece of noise. While the title track takes the cake, there are three other excellent tracks on Phaedra. "Mysterious Semblance at the Strand of Nightmares" is a solo Edgar Froese song that uses some surprisingly emotive and affecting synthesizer washes, and "Movements of a Visionary" is a more experimental piece, using treated voices and whispers to drive its hypnotic arpeggios. Perhaps even more powerful as a musical landmark now than when it was first recorded, Phaedra has proven the test of time.
