Two films on the legendary life, music, and early death of Delta blues           musician Robert Johnson, who, according to lore, sold his soul to Satan at a     crossroads in exchange for those timeless licks that became "Crossroads" and     other blues standards. Johnson's work has since influenced generations of      blues and rock artists, including Muddy Waters, Bob Dylan, Led Zeppelin, and   The Rolling Stones. Can't You Hear the Wind Howl?
