The New Orleans All-Stars Brass Band performs at the corner of Bourbon and Canal, a location that seems to recreate some of the spirit of the old Congo Square. Here the division between performers and spectators that is so much a part of Western culture is blurred, as dancers and second-liners become performers themselves, or as they occasionally borrow a drumstick from a band member and add a layer of percussion on an empty bottle. 7/4/12
