Every black guitar hero from Lenny Kravitz to Vernon Reid to Gary Clark Jr. owes Prince an immense debt of gratitude. More than any other artist since Jimi Hendrix, it was Prince who asserted to mainstream American the fact rock and roll is and will always be black music. His epic guitar solo at the Super Bowl halftime show and his virtuoso performance at George Harrison’s induction into the Rock and Roll Hall of Fame—leaving a stage full of white rock dinosaurs slack-jawed—will stand forever as living monuments to black rock.
