“I live for art; I live for love!” So sings Floria Tosca, opera diva suprema, just before she eviscerates the villainous Baron Scarpia with his own dinner knife. Passion gets like that, in both the visual and operatic arts. Join docent John Tomashek for a musical tour in the galleries, with less talking and more bel canto. Bravissimo! Focal Points is a series of gallery talks featuring topics and themes that are near and dear to the hearts of the tour guides and staff.
