I'll take you a bit off the mainstream track here. Here are a few that I've found on my frequent rotation list on a regular basis. These selections tend towards the moody and sometimes darker, low-key. They are all outstanding recordings:
Achirana which is currently only available used but well worth the price of admission IMO.
Changing Places or anything by Tord Gustavsen Trio
For Spanish Guitar, I'd point you to a different flavor:
Try
Carlos Paredes on the Portugese guitar. Very beautiful.
Of course you cannot go wrong with Andres Segovia.
Also, for a more modern interpretation, and I don't know that much about her, check out
Milica Ilic. If you search out her video's on YouTube you can get a sense of her playing. Sadly not too much on recorded music from her, but her playing is beautiful, as is she.
