Gordon Cox Theater EditorIn a Broadway season filled with star turns and individual standouts, maybe the biggest breakout performance came from … ensemble casts.From the queens of “Six” to the Thoughts of “A Strange Loop,” and from the community of “For Colored Girls …” to the triad of “The Lehman Trilogy” to the town council of “The Minutes,” Broadway rebounded from its long shutdown with a slate of shows that emphasized the collective effort that’s central to any theatrical experience. This year’s Tony nominations are packed with competing castmates from shows that highlighted the skill, the labor and the pleasures inherent in a group of talented performers simultaneously shining as individual artists and working together as a seamless whole. “Honestly, it’s why I do theater,” says Jesse Tyler Ferguson, the “Modern Family” alum now up for a Tony for his work among the cast of “Take Me Out.”His previous Broadway stint was in the one-man show “Fully Committed,” and he didn’t love going solo.
