His full name is Francisco Tostado y Carvajal. He played pieces by Fernando Sor, Ferdinand Carulli, and wrote his own music. He was the favorite student of Miguel Garcia - known as Padre Basilio who also taught Dionisio Aguado and Fernando Sor.
He played guitars fabricated by Manuel Perez and other unknown makers.
