Mexican accordionist Celso Piña, aka El Rebelde del Acordeón (the Accordion Rebel), started playing traditional music along with his brothers Eduardo, Rubén, and Enrique. In the early '80s, they turned to the tropical style after listening to Aníbal Velasquez and Alfredo Gutiérrez, forming a group called Celso Piña y su Ronda Bogotá. In 2001, Celso Piña teamed up with local rock bands Café Tacuba, Santa Sabina, and Control Machete, among others, to celebrate his 20th career anniversary by recording Barrio Bravo, produced by Alfonso Herrera and Julián Villarreal. ~ Drago Bonacich
