Quote from : A Man Without a Country Book

And I like Strauss and Mozart and all that, but the priceless gift that African Americans gave the world when they were still in slavery was a gift so great that it is now almost the only reason many foreigners still like us at least a little bit. That specific remedy for the worldwide epidemic of depression is a gift called the blues. All pop music today-jazz, swing, be-bop, Elvis Presley, the Beatles, the Stones, rock and roll, hip hop and on and on- is derived from the blues.
