Sammy Miller and the Congregation are on a mission, crisscrossing the country like a vaudevillian revival show with evangelic fervor for music. The seven-piece band, described as a mashup of Ben Folds Five and Preservation Hall Jazz Band, is putting people in the moment with a bracing dose of joyful jazz performed with infectious theatricality. The New York City-based, familial collective has captured its frenetic energy and unflinchingly optimistic songwriting on its debut album, Leaving Egypt. “We want to get people back in a room together,” Sammy Miller says. “I love the idea of being unhinged, sincere, vulnerable, and breaking down walls through humor. Music is an uplifting gift, and I want to be generous in sharing it with people.”
