M TRAIN begins in the tiny Greenwich Village café where Patti Smith goes every morning for black coffee, ruminates on the world as it is and the world as it was, and writes in her notebook. Woven throughout are reflections on the writer’s craft and on artistic creation. Here, too, are singular memories of Smith’s life in Michigan and the irremediable loss of her husband, Fred Sonic Smith. Braiding despair with hope and consolation, illustrated with her signature Polaroids, M TRAIN is a meditation on travel, detective shows, literature and coffee.
