A Diamond Anniversary
American Ballet Theatre opens its 75th season this month at the Metropolitan Opera House in New York City. And on May 15, PBS will celebrate with a new Ric Burns documentary, part of the network’s award-winning “American Masters” series. The program will chronicle ABT’s journey, from humble beginnings to international acclaim, with current and archival footage of interviews, rehearsals and performances. That means we’ll see everyone from contemporaries Hee Seo, Herman Cornejo and Alexei Ratmansky to luminaries Alicia Alonso, Twyla Tharp and Mikhail Baryshnikov.
