3. Garth Brooks Transforms Into Chris Gaines
Garth Brooks sold more albums than any other artist from the Nineties, but he was bored by the end of the decade and decided to do something radical: he created a musical alter-ego named Chris Gaines. This new persona sang pop music and had a whole fabricated backstory that Brooks planned on turning into a movie called The Lamb. Unfortunately, fans hated everything about Gaines and the whole thing dealt an incredible blow to Brooks' career.
