The Tony Award-winning Alliance Theatre won another feather for its cap when novelist Stephen King and roots rocker John Mellencamp chose the Atlanta playhouse for the world premiere of their new musical, Ghost Brothers of Darkland County. When Ghost Brothers made its long-awaited debut in April, the show's MVP proved to be T Bone Burnett as music director. Thanks to the legendary music producer and his sound design team, Ghost Brothers' tale of intergenerational family secrets sounded like a dream, with possibly the richest instrumentation and most crystalline audio clarity the Alliance Theatre has ever delivered. Burnett ensured that Ghost Brothers became a kind of sonic spectacle, from its hammering, world-shaking blues numbers to rollicking country-and-Western tunes to its supernatural sound effects. Now how can we get him back?
