In Duppies, D.S. Marriott writes a poetry of grime, the London street music, one that is "late shift, zero hour." Mixing lyric tonality with grime's aggression, grit, and speed, this is a coruscating study of the racial politics of austerity. And it is an erudite lyric, one attentive to the continuing legacies of slavery, how this history shapes and defines everything from the law to the understanding of who or what is human.
