It's great to be able to read the score as you listen to these. Brouwer has a position in guitar music similar to that of Bela Bartok in piano and violin music. The way he does new things, interesting things with rather common and basic musical materials is something only a really fine composer who is also a master of an instrument could manage. It makes me want to go buy the score and try them.
Update: Before he had to give up playing due to injury, Brouwer was a performing guitarist. Here is a good example of how he played.
