Luthier & Barrios expert Federico Sheppard and "Les Productions d'Oz" have published a 6 volume set of the complete works of Agustin Barrios Mangore in printed form called "El Libro De Oro". GSI has agreed to partner with them in producing the video companion to these beautiful publications. In this video, taken from "Volume 2: Studies and Duets" (https://tinyurl.com/y6mqk533), is an arrangement for two guitars by Barrios of Dionisio Aguado's "Coral" in a stunning performance by Sondre Hoymer on 2014 Federico Sheppard "1911 Jose Ramirez - ex Barrios" RW/AR (https://tinyurl.com/y68osg3x) and Tormund Blikra Vea on a 1929 Francisco Simplicio SP/CSAR (http://tinyurl.com/zet6euo). Recorded at the Guitar Salon International showroom in Santa Monica, CA. Huge thanks to the folks at Apogee Electronics (ApogeeDigital.com) for the use of their Ensemble interface in these recordings. http://www.guitarsalon.com/
