Daniel I am interested in the Santiago de Murcia pieces, especially La Jota. During the mid 1970's I studied with Pat O'Brien in Brooklyn. I saw the Youtube video of his performance of Murcia pieces and was reminded of his joy in playing, teaching, researching, and of course performing. I sorry to hear about his passing.
Juan Pira's discussion on finding scores has created a nice improvement to our Ning group. There is now a new menu tab, a listing of scores, and links to the various member pages where the scores can be found. For the time being I will be maintaining the the score list. Let me know if you have any suggestions/corrections for improving the list.
