Brendon Fox will direct the music-filled play about tensions within a chamber music ensemble. Performances run May 17-20. Susan A. Loewenberg will produce.

Here's how it's billed: "A world-famous ensemble threatens to unravel when its most talented member goes missing just before a high-profile performance at the White House. A young woman is hired to take his place — but with only days left to prepare, the musicians must navigate the creative, yet often disharmonious, path of creating a masterpiece. Hollinger skillfully establishes how four very distinct personalities must, in the pursuit of artistic excellence, synthesize with one another to create one seamless sound."

All LATW performances are recorded and broadcast on LATW's nationally syndicated radio theatre series, "The Play's the Thing." For more information visit latw.org. The James Bridges Theater is located in Melnitz Hall at 235 Charles E. Young Dr., Los Angeles, CA.
