 They felt that Plançon's true home lay in the French and Italian "bel canto" repertory and as a consequence of this, Boïto's snarling demon was less suited to the singer's debonair demeanour than the urbane devil that he portrayed so effectively in Gounod's "Faust".It was in the height of his glory at Covent Garden that Plançon was brought to the Metropolitan Opera in New York City by the impresario Maurice Grau.He debuted there on 29 November 1893, as Jupiter in Gounod's "Philémon et Baucis".
