“Acordeón rebelde, tu sonido / Hace bailar,” sing Calle Mambo and Kumbia Boruka on “Acordeón Rebelde.” The track, released on 27th March, is a direct tribute to the late Celso Piña, the Mexican accordionist from Monterrey known as “El Rebelde del Acordeón.” The collaboration brings together Chile’s Calle Mambo and Lyon-based band Kumbia Boruka, rooted in Monterrey, Mexico, uniting the Andean cordillera with the barrio sound of Monterrey.

The connection is personal. Many musicians from both Calle Mambo and Kumbia Boruka toured with Celso Piña on his Cumbia por el Mundo tour, learning directly from the man who took Colombian cumbia and vallenato and reworked it with rock, reggae, and hip-hop. His work, from his early days with Ronda Bogotá to his international recognition, transformed the accordion into a universal instrument. “Your accordion crossed barriers,” the lyrics state, “and with cumbia you broke borders.”

Calle Mambo, who produced the track under the supervision of Erkki Nylund, call their own sound folklor electro-urbano. For 13 years, they have combined traditional Latin American instruments like quena, charango, zampoña, tiple and ronroco with electronic production and urban rhythms. On “Acordeón Rebelde,” these Andean instruments meet the Monterrey cumbia style of Kumbia Boruka.

The band released their third album, Retumba La Tierra, in June 2025. “Acordeón Rebelde” is a standalone release supported by a video directed by Javier Astudillo, filmed at Lido Don Pablo in Naples, Italy, reinforcing the track’s global theme. The band will undertake an extensive European tour in 2026, with confirmed dates at the Montreux Jazz Festival in Switzerland and the Sziget Festival in Hungary, alongside shows in France, Spain, the Netherlands, Bulgaria, Portugal, Germany, and Italy.
