Clear Vinyl. The Mystery is an album by Australian guitarist Tommy Emmanuel that was released in 2006. The album includes the track ""Gameshow Rag/Cannonball Rag"" which was nominated for ""Best Country Instrumental Performance"" at the 49th Annual Grammy Awards. The song won ""Instrumental of the Year"" at the 2007 Country Music Awards of Australia.This album has a peace and a gentleness that emanates throughout the compositions. The song titles offer some insight: ""Cowboy's Dream,"" ""The Mystery,"" ""That's the Spirit,"" ""Footprints,"" ""Keep it Simple."" Emmanuel proves skillful without being flashy; calm without being dull; thoughtful without being pedantic. He remains faithful to the melody, using his exceptional guitar work to support the essence of the song. The record also features one of Emmanuel's most popular original songs ""Lewis & Clark,"" and a very beautiful instrumental arrangement of the Billy Joel classic ""And So It Goes."" In honor of the 20th Anniversary, this special-edition album is remastered and contains a never-released live instrumental of the Louis Armstrong classic ""What a Wonderful World.""
