The American Repertory Ballet, ARB, is seen in rehearsal for their new “Rite of Spring,” choreographed by Douglas Martin. The production celebrates the 100th anniversary of the first performances of the ballet in Paris in 1913. Those performances famously caused a riot!  Douglas Martin has a special connection to the music and ballet. He danced in the Joffrey Ballet’s famous 1987 recreation of Najinsky’s original choreography.
