Dúo Nigromante is formed by Antonio Romero García and Nun Kether Arredondo Granados, guitarists from San Miguel de Allende, Gto. Founded in January 2022, the ensemble is known for its eclectic performances that combine the order and elegance of the classical repertoire with the expressiveness and unpredictability of contemporary classical music. The result is an intriguing contrast of eras, composers, and musical languages, representing the wide spectrum of possibilities that the guitar offers as a medium of artistic expression.
