When Newton Stover III discovers the long-lost recordings of a legendary bluesman in the basement of his granddaddy’s rundown music studio, he resolves to rebuild his life and legacy. But time and money are running out fast, and the ghosts of the past — and an unexpected stranger — keep showing up. Holy Grail of Memphis is a new comedy by Philadelphia playwright Michael Hollinger about embracing the future, releasing what haunts us, and singing the blues.
