Postscript: All will tell the same story, of migration:
Alphabetically we can list a hundred names of blues and jazz greats from Perry Anderson to Muddy Waters and all will tell the same story: grew up in the South, honed their skills in the bordellos or clubs of a southern city, went on to fame, if rarely fortune, in one of the music capitals of the North or West.
Wherever the migrants ended up, a great music scene flourished. No innovation without migration.
