In 1939 Isaac Nicola continued his training in Paris with Emilio Pujol, a disciple of Francisco Tárrega.
There he continued a long lasting relationship with Cuban guitarist José Rey de La Torre, with whom he gave a concert in Havana, in 1947.
After returning to Cuba, Nicola engaged on a period of performing activity which concluded in 1957, with a concert where he premiered the famous Danza Característica by Leo Brouwer.
From then on, he devoted himself entirely to teaching, assisted by other dedicated collaborators, such as professors Marta Cuervo, Clara (Cuqui) Nicola (his own sister) and Marianela Bonet.
