Diego Blanco's classical guitar has been notoriously absent from Youtube up to now, though I have checked on his name from time to time for as long as Youtube has existed. I think he's been absent only because he has wanted to protect his copyright.
Now I happened to check on him again and the first piece I found was Asturias by Albeniz.
I have been at his concert twice in my country -- it was 1978 and 1980, if I remember correctly. I was sitting pretty close to him, so I could see his fingers, and his Asturias was really impressive -- as were all of his pieces. A shortish guy, still young back then. And a master.
In the same place where Blanco held his concerts, I also listened to Julian Bream and his lute once.
