Shortly after this was released in 1975, I heard "Legacy" on the radio and soon after purchased the LP. It has remained a favorite electronic album of mine along with Jean Michel Jarre's Oxygene and Equinoxe, Kraftwerk's Autobahn, and Tangerine Dream's Phaedra and Rubycon. It's also my favorite Synergy album, and I've heard most of them.However, look at this crummy review it got in the November 1975 issue of Stereo Review magazine - "Performance : Amateurish, Recording : Okay. -- Larry Fast, a young man who operates the synthesizer, decided to be an operator-performer after building some synthesizer equipment for Rick Wakeman. Mr. Fast has, to his credit, said of other synthesizer recordings that they were mostly technique and very little music. He inclines toward music, which is commendable. But the machine defeats him.The proof is in "Slaughter On Tenth Avenue". This is a marvelous ballet score written by Richard Rogers in 1936. It contains bittersweet, exhilarating melodies as well as harmonies and colorings which, when rendered by an orchestra of human beings - for which the piece was written to be played - make it a minor masterpiece. Filtered through Mr. Moog's invention, however, "Slaughter" is reduced to a flat one-dimensional "showpiece" for a machine that is either very misunderstood or inherently incapable of reproducing anything more musical than a modern teenager's version of "Chopsticks".The rest of the album is made up of long meandering pieces in which the operator latches onto any musical ideas he can remember from someplace else. It all sounds like a travelogue score". - J.V.I would have to disagree with this assessment and recommended you take a listen.(Note : The most recent CD includes a version of Mason Williams' "Classical Gas", which was not on the original LP).
