I am at work and can't remember the name off the top of my head, but I have an analog recording of a solo Pablo Casalis doing bach cello concertos. Real gritty sound - it needs the right system to play well and I'm not sure that I own it (sounds great over at my Dad's house). With only one instrument, you can hear pull of the bow on the strings and the resonance of sound in the instrument. I like the undisguised purity and simplicity of this disc juxtaposed with the complex music being performed. Another favorite of mine, but just because I am a Vivaldi fanatic, is CD featuring Ofra Harnoy (sp?). Exquisite cello playing. Sorry I can't give the titles. I'll try to follow up when I get home.
