Memphis Mayhem weaves the tale of the racial collision that led to a cultural, sociological, and musical revolution. Beginning with the 1870s yellow fever epidemics that created racial imbalance as wealthy whites fled his hometown, David Less moves beyond W.C. Handy''s codification of the blues in 1909 to the mid-century advent of interracial music, the birth of punk, and finally to the growth of a music tourism industry.
