The Last Days of Louisiana Red

The Last Days of Louisiana Red (1974) is a novel written by Ishmael Reed. It is considered a model novel of the Black Arts Movement and contains many elements of postmodernism. It continues the story of the character Papa LaBas introduced in Reed's previous novel, 1972's "Mumbo Jumbo". The book revolves heavily around voodoo. According to "Kirkus Reviews", "Reed's hoodoo/mojo/gris gris/Mumbo Jumbo has a wickedly funny vitality that undermines white European ideology."
