Celebrated Mexican accordion master Celso Piña died last Wednesday at 66. His skills with the instrument earned him the nickname “The Rebel of the Accordion” and he innovated the originally Colombian folk genre of cumbia by bringing in musical influences from other genres like ska, hip-hop, reggae and R&B. We’ll recap his legacy on this week’s installment of Global Notes with Catalina Maria Johnson, Worldview’s music contributor and the host of Beat Latino on Vocalo.
