Garth Brooks: Garth Brooks in the Life of Chris Gaines (Capitol)

WHEN GARTH Brooks dressed up like someone else the first time, to play the role of the wife-battering husband in the GMT- and TNN-banned 'Thunder Rolls' video, it was a brave, risky, and surprising (if still self-conscious and Madonna-ish) move. When Garth Brooks makes himself up as if he wants to be Iggy Pop's dog and issues a lite-rock concept album of the greatest hits of "Chris Gaines," building hype for The Lamb, a One Trick Pony-type film about the character that will come out next year and have its own soundtrack album, he's only aching to break the 100-million-albums barrier.
