Los Indios Tacunau is an Argentine folk music duo from Trenque Lauquen, Buenos Aires Province, formed in 1966 by brothers Nelson Abel Tacunau (lead vocals and guitar) and Néstor Eduardo “Cacho” Tacunau (second vocals and rhythm guitar). The duo gained early recognition at the Cosquín Folk Festival in 1969, where they won the Premio Revelación. Their distinctive style is characterized by an energetic, “metallic” sound created through guitar playing with picks. Throughout their career, Los Indios Tacunau released numerous albums on EMI Odeón, including Y Pa’ Qué Más... (1968). Their repertoire includes well-known interpretations of songs such as “Calle angosta,” “La flor de la canela,” and “El cóndor pasa.” The duo achieved international popularity, particularly in Japan during the 1980s and 1990s, and released other albums such as Hermanos Y Amigos (1996).
