Cardillo's richly scored and still popular 1911 romance Core 'ngrato (Ungrateful Heart) — also known by its lyric Catarì, Catarì, pecchè me dici sti parole amare — was written in America to a text in Neapolitan dialect by Alessandro Sisca; it is in fact the only famous Neapolitan song by an Italian-American immigrant.
Tomás Katari or Catari (died January 15, 1781) was an Aymara chief who, in claiming indigenous rights, led a popular uprising in Upper Peru (present-day Bolivia) in the 18th century.
