Sagreras was born in Buenos Aires. Both his parents were guitarists who taught him the guitar very early – his father was Gaspar Sagreras (1838–1901). Julio Sagreras participated in concerts from the age of 6. At age 12, he studied piano and composition. He progressed quickly and became a professor of guitar at the Académia de Bellas Artes in 1899. In Buenos Aires, he met the editor Francisco Nuñez, who later published a hundred compositions of Sagreras. In 1905 he opened his own school, Academia de Guitarra. Between 1900 and 1936, Sagreras gave many concerts in concert halls and saloons, and also participated in radio broadcasts. (From Wikipedia)
