Please read the previous review. It's very knowledgeable, with a great history of the electronic music scenes' start and rise into the 70's. Since their aren't many reviews of this great recording, I just wanted to add in my rating. I believe I still have the original vinyl lurking somewhere in my collection, but long ago purchased the original CD (which I still have) and now the newer CD version with the added track "Prelude To The Afternoon..".
I am always amazed at how Tomita somehow avoided most of the cliches of early synthesizer sounds on this and how it sounds far more recent than just about any synthesizer recording I can recall from this time period. It is evident from listening to this that Tomita (and probably this album in particular) was a big influence to young musicians at the time. Just give a listen to pop musician Todd Rundgren's 1975 36 minute piece " A Treatise On Cosmic Fire" from his "Initiation" album to hear some of the obvious influence Tomita had on the creative folk of the time.
When I listen to this (as I often do), I am reminded of how for all the improvements to modern sythesizer technology since the time this was recorded, that the actuall sounds created for the instruments haven't really improved as much as I thought they had. A testament to this record I guess!
Of course being a fan of Debussy's music will glean even more from these re-worked pieces, but you don't have to be familiar with them to enjoy this recording for everyone who appreciates quality, timeless music.
