rosa ponselle marion telva mira o norma 

On November 16, 1927, The Met introduced to Norma by Vincenzo Bellini; this opera had been a little forgotten in the first third of the twentieth century.
The cast for Norma was:
Norma: Rosa Ponselle
Pollione: Lauri-Volpi
Adalgisa Marion Telva
Orovesso: Ezio Pinza.
Tulio Serafin, conductor and director of the opera said of that night:: Norma went on stage on Novenber 16. It was a triunp, but no just any ordinary triunph. People discovered that Norma is a masterpiece, people were talking about a miracle that they had discovered in an opera that no one knew. Bellini's genius exploded from it, And for Ponselle, it was the most complete revelation imaginable.
The duo of Norma and Adalgisa is one of the masterpieces of opera and music.
