at :56 he played a D instead of the D# in the score. I heard it and then verified with slow playing. Was that intentional? or a mistake? Do classical guitarists change melody notes intentionally often? rarely? The natural D doesn't sound bad. Sounds different and interesting. I think he played it the same in the earlier part also.
la muy singular a Adelita interpretada muy bien por el profesor, Rafael Elizondo, en una guitarra de época construída por el luthier Antonio Torres. Qué maravilla !!
