Bob Dylan didn't spring fully formed. You can hear the roots of his radical vision in the styles he uncannily toggled between: ‘40s blues, ‘50s rock, ‘60s rebellion and tons more. Mississippi John Hurt's bluesy expressions of pain. Elvis' and Buddy Holly's manifestations of rock idolatry. Hank Williams' rural country. The Miracles' raw, soulful romanticism. This is the DNA of one of history's greatest musical alchemists.
