I just found a piece by Miriam Ruiz Pérez in the Cuban national socialist regime’s magazine, La Jiribilla. Apparently Borbolla was born in Manzanillo of a merchant family which made money from the hire, construction and repair of dance organs. As he moved into the business following musical studies in France, he began to replace the books of polkas, mazurkas and valses imported from France with Cuban rumbas, sons, pregons and danzons. It seems there was also a repertoire of music to be played along with live instruments. Unfortunately I can’t find any recordings of his stuff.
