Benny Moré (Bartolomé Maximiliano Moré Gutiérrez, 24 August 1919 – 19 February 1963), or Beny, was a Cuban singer. He is often thought of as the greatest Cuban popular singer of all time. He was gifted with an innate musicality and fluid tenor voice which he colored and phrased with great expressivity. Moré was a master of most genres of Cuban music, such as the son montuno, mambo, guaracha, and bolero. In particular, it is unusual for a singer to be equally proficient at both the fast rhythms (e.g. guaracha) and the slower rhythms, such as the bolero. Moré also formed and led the leading Cuban big band of the 1950s, until his death in 1963.
