Joining the previously announced Daniel Gerroll (as James) and Alicia Witt (as Beth) will be Rufus Collins, Patch Darragh and Thomas Sadowski. Amanda Charlton directs the production, which will begin previews on the Nikos Stage June 27 and run through July 8. The play, according to press notes, "explores how our culture values music, the nature of talent, and the collision of two musical sensibilities.

"[The] Bradley Quartet has arrived in New York to perform a concert, their first in America, honoring their ten years together as a group. As soon as they arrive, tensions rise to the surface. James Bradley, the first violinist and founder of the group, once expected to be the next Heifetz, feels increasingly threatened by his protégé, Hal, the group's intellectual second violinist. Then Beth, the cellist, agrees to give music lessons to one of America's biggest rock stars. As the concert approaches, the complex history of the group is revealed and the musical and personal conflicts intertwine and deepen until the entire futures of the four musicians are thrown into doubt."

The design team includes Jennifer Caprio (costume design), Marcus Doshi (lighting design), Andrew Layton (set design) and Bart Fasbender (sound design).
