Who's your guitar daddy now?

Completely different genre from anyone mentioned so far, and maybe not to everyone's taste, but for both technical virtuosity and emotionality it's hard to beat Paco De Lucía. His album 'Siroco' is a great place to start.

Jlamb - I do have one album by El Nino Josele, "Calle Ancha," and, while he's a great player, I don't find it completely engaging and my mind tends to wander, something that never happens with Paco de Lucia. I'm certainly not very knowledgeable about flamenco, thanks for the suggestion of Paco Pena.

Kijanki - two other Sharon Isbin recommendations, "Bach: Complete Lute Suites" and "Dreams of a World"

Kijanki - I'm certainly not as knowledgeable as you about Bach and I suppose I'm fairly uncritical (if that's a word.) I would describe her playing of the Lute Suites as restrained rather than energetic, more 'Sunday morning' listening than 'Saturday night.'

Thanks for the Stephen Schmidt recommendation. I really like having multiple versions of music I like, especially widely different interpretations. The first classical recording I ever bought, more than forty years ago when I was 18, was Julian Bream playing the lute suites.
