Rolando Bruno was born and raised in Buenos Aires, Argentina. After spending three years in Spain, he returned home to fully pursue his unique musical vision. His current tropical music project began in 2005, while he was still a member of the garage-punk band Los Peyotes. While Los Peyotes followed a classic rock band format, Bruno’s approach to cumbia was born in solitude, using his computer—his „best friend“—to craft backing tracks, humorously dubbing it his “MIDI Orchestra.” In 2015, Bruno expanded his sound by assembling a full band and reintroducing himself as Rolando Bruno y El Grupo Arévalo, a supergroup of underground musicians from Buenos Aires. The lineup features members of Les Mentettes, Alfonso El Pintor, Los Alamos, Los Peyotes and Pecera.
