Axl Rose and Slash

Band: Guns 'N Roses

Guns 'N Roses was part of the hair band craze of the late '80s, but there's no denying the lasting power of their album Appetite For Destruction. But while the success of that album was launching the group into the stratosphere, things were already tense between frontman Axl Rose and guitarist Slash. In fact, Rose says that he's hated Slash from day one, going so far as to publicly call him "a cancer," and boycott the group's Rock and Roll Hall of Fame induction. These two will never see eye to eye (possibly because Slash doesn't have any).
