Leib Glantz – born 1898 Kiev, died 1964 Tel Aviv; one of the most famous cantors ever, and one of the most important cantor-composers (he
sang mostly his own compositions).
See this link for his biography and
pictures (also the above picture has been copied from there); the biography states that he sang in three operas, two modern, the third La
Juive. Unfortunately, it doesn't state when and where.
Glantz was probably the most individual of all cantors;
his singing is unlikely to leave anybody indifferent. You hate him or you love him (his Machnisei rachamim
recording is a very good example).
