The quality of Jaime Delgado Aparicio´s (Lima 1943-1983) music is not only born of his natural talent, but from many years of study (mostly in the US) and investigation. From his first award for his piano skills at fifteen, to his position as conductor of the (no less) Orquesta Sinfonica Nacional de Peru, Jaime Delgado Aparicio´s career is one of no equal in Peru´s music history. We are talking about heavyweight, probably the most talented jazz musician in Peru, and maybe Southamerica. It is not frequent that an individual leaves a permanent mark in the musical history of a country. In Peru, in the 60' s and 70' s, Jaime Delgado Aparicio, a pianist and composer, promoted and exposed all different styles of jazz to all social levels, helping many young students and professional musicians to understand this musical language.
