In a lot of ways, Johnny Cash was just like Elvis. Both were sons of the Mississippi Delta; both grew up poor as dirt; both wandered in to Sun Records in Memphis in the middle of the 1950's hungry and talented; both achieved international fame and became legends in their own time. Up until 1968 or so, their career arcs show suprising similarity.
After that, they break apart to an almost perpendicular degree. The King's '68 Comeback ended up not re-vitalizing Elvis' career so much as eulogizing it nine years ahead of time. He sank down into drugs and debauchery and became just another sacrifice offered on the altar of Fame, apotheosized in mystic sightings and velvet portraits. Only now, 30 years after his death, are the cognoscenti prepared to take him seriously again.
