Fun arrangement of this classic guitar work by Paraguayan composer/gutiarist Agustín Barrios Mangoré, (1885–1944). This is an arrangement of the 3rd movement (Allegro solemne) of La Caterdral played by Julien Labro & the Spektral Quartet. When bandoneon gets in there I can’t help but think Piazzolla! This comes via Azica Records on YouTube.
If you don’t know the original guitar version here is Berta Rojas playing the Allegro Solemne from La Catedral by Agustin Barrios.
