Carlo Tagliabue (January 13, 1898 – April 5, 1978) was an Italian baritone.
After studies with Leopoldo Gennai and Annibale Guidotti he made his debut in Lodi, Lombardy, in Loreley and Aida. His debuts in Genoa (1923), Torino, La Scala (1930), Rome (1931), and Naples (1931) were all in Tristan und Isolde (sung in Italian). He also performed in Wagner’s Götterdämmerung, Tannhäuser and Lohengrin. However, Tagliabue would go on to excel in the Verdian repertoire, especially La forza del destino, Aida, Rigoletto, La traviata, Nabucco, and Otello. He created the role of Basilio in Respighi’s La fiamma in 1934.
His international career included Buenos Aires’ Teatro Colón (1934), the Metropolitan Opera, New York (1937–39), and San Francisco Opera and Covent Garden, London (1938). Tagliabue’s last performance was in 1955 at La Scala, at the famous performance of La traviata conducted by Carlo Maria Giulini and directed by Luchino Visconti, where Maria Callas scandalized the public by throwing her shoes off.
