A celebration of New Orleans’ musical culture — from its piano bars and barrelhouses to brass bands and street parades, with their colorful, riotous, and symbolic second lines, in which the community plays an essential part in the performance. Archival film footage, photographs, interviews with and performances by the Preservation Hall Jazz Band, the Dirty Dozen Brass Band, Mardi Gras Indians, and Danny Barker tell the story of the New Orleans tradition.
