Horrible guitar concerto? Apparently the man actually WANTS to be lynched.
I would disagree with the term "horrible" (and it looks like he was just joking too), but I have to say the Aranjuez is not my favourite guitar concerto either. It seems to be the guitar equivalent of the Dvorak cello concerto: guitarists are forced by popular demand to play this same work over and over.
Well, one cannot ignore popular demand; my very definition of a great work is one that has a certain whatever-it-is that makes it appealing across many times and cultures, and by this measure, the Rodrigo concerto is a great work and deserves to be played as often as the public wants it. It does seem a pity though when such works end up completely overshadowing everything else.
