"Assassins provides a darkly-comic, captivating look at the lives, loves, and lunacy of nine infamous American assassins — from John Wilkes Booth to Lee Harvey Oswald to John Hinckley Jr. — who attempted, successfully or not, to take the lives of American Presidents," according to Signature. "One of the most innovative musicals in years, [its] score ranges from folk to ragtime to big Broadway ballads…" Joe Calarco directs. For more information, visit www.signature-theatre.org.
