Opera Singer. A tenor with a repertoire of about 150 roles, he is remembered as one of his generations more distinguished comprimarios, the artists called upon to go onstage almost every night portraying a wide variety of characters in a multiplicity of languages. Originally trained by soprano Rosetta Pampanini, he later studied at the Conservatory of Venice with another distinguished soprano, Gilda Dalla Rizza. Andreolli made his June 6, 1948 professional bow with a recital of opera arias at the Teatro Ferrini of Adria then after winning a 1950 vocal competition was first seen on the operatic stage in January 1951 at La Finice di Venice as Gherardo from Puccini's "Gianni Schicchi". Over the years he appeared in numerous major venues, bowing in London and Paris in 1960, Lisbon in 1964, Geneva in 1965, Buenos Aires in 1967, and at New York's Metropolitan Opera in 1968, while performing at most of the major Italian theatres including La Scala Milano, the Arena di Verona, and Florence's Maggio Musicale. Andreolli's list of characters included at least three roles from Puccini's "Turandot" and four from Jacques Offenbach's "The Tales of Hoffmann", Cassio and Roderigo of Verdi's "Otello", Goro from Puccini's Madame Butterfly", the Abbe and the Incredible in Umberto Giordano's "Andrea Chenier", Remendado from Bizet's "Carmen", Beppe of Leoncavallo's "I Pagliacci", Maestro Trabucco from Verdi's "La Forza del Destino", Baron Scarpia's evil henchman Spoletta in Puccini's "Tosca", and at least one major role, the dimwitted Nemorino of Donizetti's "L'Elsir d'Amore". He occasionally sang in oratorio presentations, gave his 1994 final performances at Teatro Regio di Parma as Masil from Mussorgsky's "Boris Godunov", never officially retired, and died of a stroke. He can be heard on a number of studio recordings and archived broadcasts.
