This recording had to do some work to win me over, but it did. I'm not fond of transcribed music; I like music with original instrumentation. To me, lute music is for lutes, not guitars; harpsichord is for harpsichords, not pianos. This is the first transcribed album I liked well enough to buy at the first go around. It is simply marvelous; and while there are passages where I would prefer the quickness and sharpness of a lute, I have grown to love this one. I'm not much of a classical guitar fan, either, but I finally realized why this music appeals to me: It is the work of a real composer, with length and depth and variety and purpose.
I have always thought that when J.S. Bach imagined music, he imagined it on a harpsichord. I think this weakens his string music; the endless sawing away of violins on eighth and sixteenth notes--far better suited to a harpsichord--irritates me. But with the guitar or lute, it works much better. And when Bach (through Williams) slows down and lets the melody speak... heavenly.
What Williams has done, that matches the harpsichord paradigm, is play the guitar (as others have noted) with two voices, as with the upper and lower keyboards of a harpsichord. In this I think he has gotten inside JSB's mind, and understands what Bach was doing. I have never heard anyone else pull off the two-voice effect like this. Almost three-dimensional. Marvelous.
