niiiiiiiice! My only comment is that I truly adore the original Wendy Carlos Moog Bach, so I'm in a slight dilemma about whether adding recorder to that heavenly effect is a good or an unnecessary thing - but whichever way it goes, it's a thing that I'm glad someone tried! Bach's a strange one, because his music more than anyone's seems to do well when used on all sorts of odd instrumental combinations, but nevertheless it's not true (in my opinion) that it neglects the atmosphere of the instrument. It just seems to be open to new interpretations.
I have this theory that musical instruments are like a human life-span. There is a period when a human is very young, that they believe they can do anything, they're fresh and energetic, but often rather lacking in subtlety, which can be charming in itself - and they copy the adults but with completely unique youthful zest, unaware that they're not doing the same thing at all! The synthesiser was definitely at that stage when the famous Bach versions came out.
Aren't we lucky there is so much lovely stuff out there to explore, both listening and playing?
