I have a couple suggestions for classical guitar. First, try anything by the Spanish composer Rodrigo. I suggest looking at Phillips' "Complete Concertos for Guitar and Harp" (2 CD's).
Second, my absolute favorite classical guitar music is from a classical CD collection I got at Sam's Club. The two in particular are called "The Art of Classical Guitar" and "Guitar Masterpieces", performed by the St Cecelia Symphony Orchestra and sold my Direct Source Special Products, Inc. (Item #GC16502 and GC16512). These are absolutely beautiful recordings of popular classical pieces (Beethoven's Moonlight Sonata, Pachelbel's Canon, Schubert's serenade, etc) performed on the guitar.
Good luck!
