Segovia's protege & heir, the wonderful Eliot Fisk. This is his collection of Paganini violin caprice transcriptions for solo guitar. Please clear space on the floor for your jaw :) :

Another master, John Williams, plays masterpieces of classical guitar concertos by Vivaldi, Rodrigo, Villa-Lobos & (a fave of mine) Castelnuovo-Tedesco. Really amazing stuff here:

Another master Julian Bream, another good intro collection of standard repertoire pieces (Vivaldi, Villa-Lobos, Albeniz):

Those are four of the best in the field in my opinion. And if nothing else, a great place to start. Have fun!
