Sugarland, an American country music duo, is composed of singer–songwriters Jennifer Nettles (lead vocals) and Kristian Bush (background vocals, lead vocals, mandolin, acoustic guitar, and harmonica). Sugarland was founded in 2002 by Kristen Hall with Bush and ultimately became a trio after hiring Jennifer Nettles as lead singer. After three years, Hall left the group.
Signed to Mercury Nashville Records in 2004, Sugarland broke through that year with the release of their debut single "Baby Girl", the first single from their multi-platinum debut album Twice the Speed of Life. The trio became a duo in 2006, when they also released their second album, Enjoy the Ride. This album produced their first two No. 1 singles (in the U.S.), "Want To" and "Settlin'", and won the duo a Grammy for "Stay". In 2008 they released their third album, titled Love on the Inside. This album produced three more No. 1 singles with "All I Want to Do", "Already Gone"and "It Happens". Their fourth album, The Incredible Machine was released on October 19, 2010 in both a standard and deluxe edition. Upon The Incredible Machine being certified platinum, Sugarland has sold in excess of 14 million records. Nettles and Bush also write all of the band's songs.
