Callas's dissatisfaction with the La sonnambula recordings may have stemmed from a disagreement with conductor Tullio Serafin over vocal ornamentation, which was reduced to a minimum.
Maria Callas initially withheld approval for the La sonnambula recordings on this album, postponing its release indefinitely.
This album presents the recorded material in the order originally intended for an LP release that never took place during Maria Callas's lifetime.
This album features recordings made by Maria Callas with conductor Tullio Serafin just two days after her greatest triumph in La traviata at La Scala in May 1955.
The La sonnambula material on this album was only released after Maria Callas's death in 1978, on an LP titled Maria Callas - The Legend.
Maria Callas, the soprano on this album, achieved a series of spectacular successes at La Scala, particularly in rarely performed operas like Medea, La vestale, and La sonnambula.
