Answer by taking a quote from the following article:

Taylor Hicks was born in Birmingham, Alabama on October 7, 1976, to Bradley Hicks and Pamela Dickinson. He and his family moved to the suburb of Hoover when he was eight years old. His hair started turning gray by the time he was 14. His parents divorced, and stepmother Linda shared custody of their son until he became of age.

While in college, Hicks was part of a band called Passing Through, which he later quit to start his own band. In 1997, he independently recorded In Your Time, an album which included both studio and live tracks. In 2000, he moved to pursue a music career in Nashville, Tennessee, where he worked with Nashville veterans Billy Earl McClelland and Percy Sledge to record a three-track demo but was unable to find a label that would sign him. He left Nashville after a year due to what he called the "oversaturation of the market". Hicks returned to Alabama and launched a professional music career, performing at various venues and parties mostly around the Southeastern United States, including The War Eagle Supper Club (a popular college bar) in Auburn, Alabama. Hicks has performed with the likes of Widespread Panic, James Brown, Tom Petty, Jackson Browne, Drive-By Truckers, Robert Randolph, Snoop Dogg and Keb Mo. He also performed in the huge infield of Talladega Superspeedway in 2004 during a NASCAR race weekend.  He recorded, produced, and released a second album, Under the Radar, in 2005. Despite releasing two albums prior to appearing on American Idol, he did not violate their requirements for contestants, as he had never held a recording contract.  Hicks has allowed audience members to record his concerts for personal, non-commercial use, and has authorized the Internet Archive to create a section for fans to upload and share their recordings. The Archive does not accept the upload of concerts recorded after January 1, 2006 due to the terms of his "American Idol" contract.

Did he release any other music?
Hicks has performed with the likes of Widespread Panic, James Brown, Tom Petty, Jackson Browne, Drive-By Truckers, Robert Randolph, Snoop Dogg and Keb Mo.
