A fine performance, MG. Thanks for posting it!
The Cinco Preludios are quite enjoyable to learn and play, though I'd admit that I don't really like the 1st, Preludio Rockero. I had a lesson with Maestro Pujol back in 2010, and we worked on #2 and #3. I brought the UE edition, and Maximo found a bunch of mistakes in Tristango en vos. Incidentally, Jason Vieaux recorded it as published, complete with the errors!
Enjoy the process!
