I just saw that there is a new book called El Libro de Oro, Volume 1 - The Barrios Method. I haven’t ordered it but I may check it out at some point. If anyone has it, leave a comment below with your thoughts.
New Barrios Edition in 8 Volumes
75th Anniversary Edition
The most complete edition of Barrios ever published
Based only on source manuscripts from the hand of Barrios and his direct pupils.
