Where to start....
Manuel Barrueco: Mozart and Sor (probably my favorite guitar recording), J.S. Bach Sonatas, "Plays De Falla, Ponce, and Rodrigo" (contains my personal favorite performance of Invocation et danse), 300 Years of Guitar Masterpieces (3 CD set, nearly a must own for any serious classical guitar aficionado)
David Russell: Bach, Fancisco Tarrega, Message of the Sea, Music of Barrios, 19th Century Music
John Holmquist: Garcia: Etudes Esquisses / Celtic Airs
John Williams: The Black Decameron
John Williams and Timothy Cain: The Mantis and the Moon
Odair Assad: Fuga y Misterio
Sergio and Odair Assad: "Rameau, Scarlatti, Couperin, Bach", Jardim Abandonado (really impressive interpretation of Rhapsody in Blue here)
Scott Tennant: Joaquin Rodrigo: Complete Guitar Works
William Kanengiser: Rondo Alla Turka, Echoes of the Old World
Just about any of the Naxos recordings that were prizes for GFA winners including Martha Masters, Kevin Gallagher, Frano Platino, and many others. Just about anything by LAGQ.
That's a good start.
