The composition process of "Tumbao" and "Cumbia Concerto" involved extensive historical, technical, and stylistic research to ensure the authenticity of my fusion of styles. While I am not an expert in Afro-Cuban music, my compositions draw from valuable sources, including recordings of salsa, bachata, cumbia, and reggaeton legends. To make these works more accessible, I am offering the full rhythm section part at a discounted rate. I hope my reinvention of these wonderful music styles brings joy and inspiration to both casual and serious musicians. Knowledge is power—use it wisely.
