Biographical notes from cantabile-subito:
American-Italian soprano, 1902 - 1986
She was born in Philadelphia to Italian parents and studied with her father, Ferruccio Giannini, who was a tenor and ran his own opera company. Her mother Antonietta Briglia-Giannini was an excellent violinist. She was immediately given singing lessons by her father. Dusolina’s sister was also a singer, one of her brothers became a cellist and the other one a well-known composer. At the age of thirteen she sang Azucena in her father’s company. Later she continued her studies with Marcella Sembrich . And it was in New York where there was the scene of her first triumph. She substituted for the indisposed Anna Case at a concert in Carnegie Hall. In 1924 she started recording for the Victor company. The same year she was very successful in London. In 1925 she made her debut as Aida at the Hamburg State Opera. She appeared there until 1930. In 1928 she sang a number of highly successful performances at Covent Garden. She was invited to sing Aida in a complete opera recording (her partners were Pertile, Minghini-Cattaneo and Inghilleri under Sabajno). This recording enjoyed almost legendary fame and familiarized her name throughout the world. She never actually sang at La Scala. In 1934/35 she appeared as Donna Anna at the Salzburg Festival. Guest appearances took her to Monte Carlo, Zurich, Oslo, Amsterdam, San Francisco and Mexico City. In 1936 she made her Met debut as Aida and remained a member of the Met ensemble until 1941. She continued to sing in Europe. After 1962 she was director of the Opera Studio in Zurich.
