Hard to summarize. Dense and ambitious cultural criticism focusing on African American culture, with particular attention to counterfeits, masks, variable personae, and truthful lies. There's quite a bit about how African American writers and musicians did modernism and postmodernism before they were named, and how their work and fantasies of black people were appropriated and incorporated into the work of the white writers of the canon. The focus is mostly on African American works and their centrality to American culture. I particularly liked the bit talking about the elevator as a recurring symbol in African American literature.
It gave me a long list of writers to read, reread, or catch up with.
