Mark, you didn't indicate about how many "some" is, but I ran through Classical Instrumental from A to Z. I didn't pick Parkening, Romero, Segovia or Williams. Go with David Russell's Bach Collection (Selection # 1463710)and Sharon Isbin's Spanish guitar concertos(#1617844). Then I saw a very attractive collection of harp transcriptions by Yolanda Kondonassis(#1516244). If you didn't get the Dvorak Slavonic Dances that I've been recommending, they have a good one(#1447366). The highly-acclaimed Hamelin piano collection featuring the Albeniz Iberia is available(#2613750). Dozens more possible, of course.
