strange no details of this release at all.

Sure, it's a non conventional interpretation of Bach.
But in fact, he further claims "the suitability of the textural clarity inherent in synthesized electronic sounds, to enhance the Baroque traits of crisp sonority, terraced dynamics and the high relief of different voices" (as perfectly write Peter Gutmann).
As an admirer of Bach and Moog music, it's perfect record. Even if the gap is extremely large, and the experience disturbing, between the majesty of the compositions and the funny connotation of Moog sounds.

Stanley Kubrick, after listening to this success release, decided to work with Carlos for his masterpiece "A clockwork Orange", and find the perfect resonance to his images, the perfect strange mix this music create in minds.

Personally me, I find the whole W. Carlos ouvre taste-less. He once was a great pioneer, and one of the first working entirely on such modulars but I don't like his/her albums. Lack of real spice, good sonic timbres and spirit of all. Very well done and pioneer job. But somehow I never have any intentions to listen any. I prefer ISAO TOMITA. His conception comes dreivative from W.C. but he went much further: each, every tunes and timbres are wonderfully charactheristic, deep, empotional, or funny, yet very grandioso and dramatic. Tomita IS the man at the field of analog modulars. He playes almost everything like no-one else. As a Debussy, Ravel and Bach -collector, I must say: he plays all exceptionally good, and the same time he has an incredible sonical and personal character what W.C. absolutely lacks of. W.C. is one of the most important name but if it comes to enjoy the music, only ISAO TOMITA comes in question. For me W.C. almost uninteresting even if I have a very huge collection of electronic music and I'm very much into the synthesis also. By now, I know the value of all...

the labels for this issue shown here are the repress issues and should be moved to the repress release page. Original labels are medium gray with white lettering around edges with 360 sound, stereo, 2-eye, and black print for titles/artists.

One of the most important electronic music recordings of all time. Carlos plays the Moog like no other. This is a must if you want a comprehensive electronic music education.
