<i>Aprender Es Infinito</i>: El Comandante Mario Rivera, the Godfather of Dominican Jazz

Abstract The Dominican American saxophonist, multi-instrumentalist, and bandleader Mario Rivera (1939–2007) began his career as a master sideman in the best New York Latin dance bands of the twentieth century. An avid reader and organic intellectual, Rivera fed his musical growth by surrounding himself with the top Latin and jazz musicians on the scene, converting his Manhattan apartment into a veritable salon for creative music where the best musical minds of the twentieth century, such as Tito Puente, George Coleman, and Thelonious Monk, converged to trade ideas and make music. Notable for his prowess as a doubler, Rivera played more than a dozen instruments, ranging from saxophones and flutes to congas, trumpet, and vibraphones. Expanding on his experience playing Latin dance music, Rivera worked as an improvising soloist with many of the most creative African American musicians in jazz. Rivera's most significant contributions reside in his innovations blending merengue and Afro-Dominican ritual drumming with jazz. Although he is acknowledged as an extraordinary talent among aficionados, Rivera never received major recognition in the annals of music history, perhaps because he primarily worked as a sideman and small-group bandleader focusing on Dominican jazz. Mario Rivera's historical significance as a contributor to the development of modern music therefore challenges prevailing narratives of the development of Latin jazz, which emphasize Afro-Cuban genres and Puerto Rican musicians, often neglecting the contributions of musicians from the Dominican Republic.
