Greatest Hits, also titled Garth Brooks in... The Life of Chris Gaines, is an album by American country music artist Garth Brooks, in which Brooks assumes the fictitious persona of Australian rock artist Chris Gaines. Originally, this album was intended to be the soundtrack for a movie called The Lamb that would star Brooks as a rock star recalling the different periods of his life. This album was purposely released a year in advance from the scheduled film release date to pique interest in Brooks performing rock instead of country. The Lamb, however, was never filmed due to financial and management problems.
The album was released on September 28, 1999. It reached No. 2 on the Billboard 200 chart, and also gained Brooks his first and to date only appearance in the top 40 of the US Billboard Hot 100, with "Lost in You", which peaked at No. 5. The track "It Don't Matter to the Sun" was later covered in 2005, by Rosie Thomas on her If Songs Could Be Held album.
On November 13, 1999, Brooks hosted Saturday Night Live as himself but performed the musical number ("Way of the Girl") as Chris Gaines without acknowledging to the audience that they were the same person. The album had disappointing sales compared to Brooks' previous albums, with some citing Brooks' image change of wig and make up, and the album's rock-star concept for this fact.
