The cavalcade forms up. In beats, without words, the drummers argue a bass line. While higher registers wait in silence, contraltos and bassos scat and moan, improvising the tune (the lyrics never change). The soulful melodies these deeper voices come up with are much too cool, and none capture the hot quiddity of their subject. “Make dat shit bump, y’all,” a counter-tenor exhorts. “Put some stank on it!” So the music picks up funk and swing. A girl bounces and stretches with the other dancers. They have black skin, or brown, or golden; hers is gray, waxen, and flyblown. What ails this girl, her bones slipping so weirdly in raddled tissues?
