Restless Heart is an American country music band established in 1984. The band's members are 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 and chose Verlon Thompson as the original lead singer, but he was replaced by Stewart in this role before the band had recorded any material. 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 rotating as lead vocalists in his absence. 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 band 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. Overall, Restless Heart has released seven studio albums and two greatest-hits albums. Their second through fifth albums are all certified gold by the Recording Industry Association of America, and 26 of their singles have entered the Billboard Hot Country Songs charts, including six that reached number one. Four of their country releases also crossed over to the Adult Contemporary chart, with two of those ("I'll Still Be Loving You" in 1987 and "When She Cries" in 1992) also reaching top 40 on the Billboard Hot 100. The band also had a number one on Adult Contemporary in 1993 with "Tell Me What You Dream", a collaboration with Canadian smooth jazz saxophonist Warren Hill. Restless Heart's sound is defined by their country pop arrangements and vocal harmony, with many critics comparing them to the Eagles.
