When people from Australia or Japan or Italy say, 'Oh, I love the blues,' they're not talking about the Southwest blues styles, the Georgia 12-string players, ragtime Piedmont styles or whatever. It's the Delta blues. If you say, 'Who do you like?' they'll name Robert Johnson, Muddy Waters, John Lee Hooker, Howlin' Wolf, Son House - Dick Waterman, to Francis Davis, quoted in Davis' book
