My first exposure to the music of Perrey & Kingsley was when a friend turned me on to "The In Sound From Way Out" back in 1966.
I was blown away by what could be done with tape, synthesizers (then a very new concept), and this interesting little instrument called the Jenny Ondioline. It was this same instrument, by the way, that carried the melody in Kai Winding's version of "More", back in 1963. The early synthesizers could only produce one note at a time, and were incapable of producing the multi-layered sounds that today's instruments can. So you can imagine how painstaking the task of recording, assembling, and splicing everything together to produce these songs.
This set puts, in one place, all of the recordings Jean-Jacques Perrey and Gershon Kingsley did for Vanguard Records. The first two albums, "In Sound" and "Spotlight On The Moog: Kaleidoscopic Vibrations", appear in their entirety on disc 1 of this three disc set. Both sound totally amazing here, the best I've ever heard them. I had a copy of "The Essential Perrey & Kingsley", but this blows that one away sonically. Also, the last track on "Kaleidoscopic Vibrations" was switched with something that had been previously unreleased. On this set, it's fully intact. All tracks, with two exceptions, are essentially novelty tunes. All the "beeps, pwaa-pwaas", and similar electronic effects, along with movement of sounds speaker to speaker, are there. The two exceptions take a more serious approach without all the fancy effects. Those tracks, "In Sound"'s "Visa To The Stars", and "Kaleidoscopic"'s "Pioneers Of The Stars" (the track that was replaced on "Essential"), are fitting end tracks for these albums. "Visa" is very reminiscent of the Kai Winding track mentioned above.
The second disc puts two solo albums by Perrey together for the first time. These albums, "The Amazing New Electronic Pop Sound of Jean-Jacques Perrey", and "Moog Indigo", follow in the tradition of the two albums collaborated with Kingsley. I'm not getting into track-by-track descriptions here, because you gotta hear 'em for yourself. The only one I'll mention is the final track from "Moog Indigo", which is called "Passport To The Future". This track, incidentally, was covered by The Ventures as "Skylab". This track is another fitting finale to the album, again more straightforward than the other tracks preceding it. In my earlier days, (Jeez, I'm making myself sound old), I used to send tapes to friends with music and narration on them, and the track I generally ended the tapes with was "Passport". It just worked!
The third disc in this set, which I must admit I haven't listened to, features remixes of several tracks by such "artists" as Fat Boy Slim and Eurotrash.
In summary, this is a set that you should listen to if you have a sense of humor and really want to hear what your stereo can do. Electronic music can really task a system's grasp on reality, since no one knows exactly what these sounds should sound like. But it's a fun listen, and I recommend it highly.
