An incredible achievement, 13 year old German guitarist Leonora Spangenberger plays the complete set of 12 etudes by Heitor Villa-Lobos (1887-1959). Leonora is a student of the amazing Stefan Schmidt. This comes via his YouTube channel where he highlights some of his great students. Schmidt has a ton of great students highlighted on his YouTube, all doing very well. Congrats to both of them on an amazing job. I recommend this newer sheet music edition via Amazon: Villa-Lobos Preludes (Zigante) or you can get the old complete solo works.
