I often play classical or Spanish guitar for an evening dinner party. It's makes a nice unobtrusive background, and is also relaxing and stimulating at the same time. There have been at least two Spanish guitar threads in the not to distant past which provide some excellent selections. A new classical guitar release that I just happened upon at a favorite store is by Paul Galbraith - French Impressions (Debussy & Ravel) seems to meet your criteria well. Good luck.
