In the following Met seasons, Ponselle's roles included the lead soprano roles in "La Juive" (opposite Caruso's Eléazar, his last new role before he died), "William Tell", "Ernani", "Il trovatore", "Aida", "La Gioconda", "Don Carlos", "L'Africaine", "L'amore dei tre re", "Andrea Chénier", "La vestale", and in 1927 the role that many considered her greatest achievement, the title role in Bellini's "Norma". In addition to her operatic activities, which were centered at the Met, Ponselle had a lucrative concert career. A tour of the West coast included an appearance at the Lobero Theatre in Santa Barbara on March 14, 1927 in the Artist Series of the Community Arts Association's Music Branch, accompanied by pianist Stuart Ross.
