I am not aware of a full collection of Torroba's guitar music.
Thanks, David. I was afraid that that would be the case. So, I guess I have to find an index of the complete guitar works of Torroba, and then search for CDs with the individual pieces until I have them all.
I don't know either any complete recording.
Pepe Romero has recently recorded several concertos for Naxos. But not all of them yet (there are 9 guitar concertos by Torroba).
There is an old double-CD by Opera Tres with some rarely recorded/performed pieces, such as Piezas de Albun, 3 preludios, Sonatina y Variacion, Puertas de Madrid.
