Restless Heart is an American country music band established in 1984. The band's longest-lasting lineup has consisted of Larry Stewart (lead vocals), John Dittrich (drums, vocals), Paul Gregg (bass guitar, vocals), Dave Innis (piano, keyboards, guitar, vocals), and Greg Jennings (lead guitar, mandolin, vocals). Record producer Tim DuBois assembled the band to record demos; Verlon Thompson was the original lead vocalist, but he left and was replaced by Stewart before the band had released any singles. Between 1984 and 1998, Restless Heart recorded for RCA Records Nashville, releasing the albums Restless Heart, Wheels, Big Dreams in a Small Town, Fast Movin' Train, Big Iron Horses, and Matters of the Heart. Stewart left for a solo career before Big Iron Horses, which resulted in Dittrich, Innis, and Gregg alternating as lead vocalists; Innis also departed before Matters of the Heart, and the band ultimately went on hiatus from 1994 to 1998. During this time, Jennings became a member of Vince Gill's road band, and Dittrich recorded one album in The Buffalo Club. Outside a brief reunion for new tracks on a Greatest Hits album in 1998, the band remained inactive until 2002, when Dittrich, Gregg, Innis, Jennings, and Stewart resumed touring. Two years later, they issued Still Restless on Audium Entertainment.
