Chris Gaines

Garth Brooks released his first -- and only -- album as Chris Gaines on Sept. 28, 1999.

Twenty-two years ago, Garth Brooks pivoted at the height of his fame to do something ... uh, let's call it "unexpected."

Brooks released 'Chris Gaines: Greatest Hits' on Sept. 28, 1999.

"I love that project, so I'm excited," says Brooks.

The 'Behind the Music' episode gives its viewers a number of insights into Gaines' entirely fictional life.

On Nov. 13, 1999, Brooks performed double duty on NBC's 'Saturday Night Live'.
