The remarkably rich and raucous character-driven songs, by Bon Jovi cofounder David Bryan, lovingly capture the insinuating, earthy authenticity of rhythm and blues, gospel and early rock and roll without sounding derivative. The moody and inventive production has been put together with down-and-dirty elegance by director Christopher Ashley, choreographer Sergio Trujillo, set designer David Gallo and costume designer Paul Tazewell, who let the musical and dramatic and pop-up scenic discoveries peel off one another at a pace breathless and disciplined, original and authentic. When a singer lets loose - and, eventually, they all do - the vocal pyrotechnics come from deep within the storytelling.
