Query: Interesting music

I do not know classical guitar well - but this is a series of really wonderful pieces. I keep it on in the background when I am writing. One of the pieces has a 12 note Exercise which a banjo player would call pulling off - basically plucking the string to get it to sound. On the banjo a 3 note one is tough - so I was especially impressed. But the music is lyrical and really quite nice.
