Smooth jazz is a popular genre of music that grew out of jazz and is influenced by rhythm and blues, funk, rock and roll, and pop music styles (separately, or, in any combination). Musicians such as Kenny G., Ramsey Lewis, David Koz, and Spyro Gyra have had hits with instrumental recordings, while singers such as Anita Baker, Sade, Sting and Norah Jones have found success with vocal releases. George Benson remains a popular Smooth Jazz artist as both a singer and guitar player.
