Campbell's father was a gospel singer, though he was raised by his grandparents. Campbell moved to Nashville after his brother, Spencer, launched a professional career there. He became a songwriter for Tree Music, and released his first album as a solo artist in 1992. Three singles from his debut album hit the Billboard Country singles chart.
In 2004, Campbell's first novel, Cottonwood, was published. The book is set in West Texas in 1937. Included with the book is a CD which features 12 original tracks inspired by the novel.
In recent years, Campbell has expanded his career and moved behind the scenes, working as a producer and director in music videos and short films. He is one of the founders of Gravel Road Productions, which produces Bronco Roads, a PBS travel series that showcases New Mexico. Campbell serves as host.
