Julio Sosa (guitarist)
Julio "Koko" Sosa is a master guitarist and composer from Ucacha (Cordoba Province), Argentina.

Career
Sosa performed throughout Latin America and the United States, including performances at the White House and the Kennedy Center in Washington, D.C., and was for many years an instructor at the Guitar Gallery in Washington, D.C. Hailing from Argentina, he was known in South America as "Koko Sosa" (not to be mistaken for producer and actor Manueal "Coco" Sosa). He specialized in Argentine idioms like the Tango, Milonga, Chamame, Zamba, Tonada, and Aires Criollos. Among well-known figures he worked with in South America were the legendary Argentinian singer-songwriter Mercedes Sosa (not a relation). He died in Washington D.C. in 2014. References
