Another track from the album, "Hummingbird", was later recorded by Ricky Skaggs on his 1989 album "Kentucky Thunder", and was a top 20 country hit for him in 1990. Tom Roland of "Allmusic" wrote that "[t]he guys found their niche with this project. Big, overpowering sound, heavy backbeats, and very tight harmonies are here." The band's third album, "Big Dreams in a Small Town", came in 1988. From it came two more number ones: "The Bluest Eyes in Texas" and "A Tender Lie", as well as top-five hits in its title track and "Say What's in Your Heart". The latter of these was also a number one on the "RPM" country charts in Canada. This album was also the first to feature members other than Stewart on lead vocals: Gregg sang "El Dorado" and shared lead vocals with Stewart on "Carved in Stone", while Dittrich sang "Calm Before the Storm". The band members wrote some of the songs themselves, while others were co-written by outside writers, including "A Tender Lie", written by Randy Sharp. "People" gave the album a positive review, noting the band's musicianship and prominent vocal harmony, as well as the "considerable amount of passion" in their music relative to their contemporaries. Restless Heart's fourth album, "Fast Movin' Train", was released in 1990. Its title track (also written by Loggins) and "Dancy's Dream" were top-five hits, while "When Somebody Loves You" and "Long Lost Friend" were less successful. Robert K. Oermann of "The Tennessean" found this album superior to the ones before it, praising the "direct approach" of the singles' lyrics, while also noting a roots rock influence in the increased use of acoustic instruments over the preceding albums. Stewart also sang backing vocals on "They Just Don't Make 'em Like You Anymore", a track from Kenny Rogers' 1991 album "Back Home Again". A greatest hits package, "The Best of Restless Heart", followed in 1991. It included two new recordings, both of which were released as singles: "You Can Depend on Me" at No. 3 and "Familiar Pain" at number 40. Larry Stewart left the band in 1992 to pursue a solo career, also on RCA. His solo debut single "Alright Already" reached No. 5 on the country music charts in 1993.
