Puccini’s heartbreaking story of young love in the garrets of Belle Epoque Paris has attracted many famous singers through the years. But with James Levine at the helm and the starry duo of Luciano Pavarotti and Renata Scotto as Rodolfo and Mimi, every bit of emotion in the score pours across the footlights and seduces the audience. In this case, the audience was in the millions since this was the very first in the “Live from the Met” series of telecasts. The evocative production is by Fabrizio Melano, designed by Pier Luigi Pizzi.
