Agustín Pío Barrios (also known as Agustín Barrios Mangoré, May 5, 1885 – August 7, 1944), was a Paraguayan classical guitarist and composer. Barrios is still revered in Paraguay to this day, where he is seen as one of the greatest musicians of all time by many. John Williams has said of Barrios: "As a guitarist/composer, Barrios is the best of the lot, regardless of era. His music is better formed, it's more poetic, it's more everything! And it's more of all those things in a timeless way."
