Renato Zanelli-Otello- "Ora e per sempre addio-" 1929

A very talented but largely unheralded tenor, Renato Zanelli, sings an excerpt from Otello in this historic 1929 recording from London's Covent Garden. I love the exemplary breath control 1:45-1:55 in that seamless shift up to the B flat. Very impressive.
Renato Zanelli (April 1, 1892, Valparaiso - March 25, 1935, Santiago) was a Chilean operatic baritone and later tenor, particularly associated with heroic Italian and German roles, notably Verdi's Otello. His New York Metropolitan Opera debut came in 1919, as Amonasro. He remained there until 1923, singing most of the major Italian baritone parts.
Zanelli then left for Italy for further studies with Dante Lari and Fernando Tanara in Milan. His first appearance as a tenor occurred in 1924 at the Teatro San Carlo in Naples, as Raoul. He went on to sing widely in Italy and South America in roles as diverse as Pollione, Don José, Andrea Chenier, Canio, Tristan and Siegmund.
Zanelli had a rich voice and was equally successful as a baritone and a tenor, his early death from cancer cutting short a brilliant career. His artistry is preserved, however, on a number of recordings of operatic arias which he made at the height of his powers in the two vocal categories that he had mastered.
