Diamond Rio is an American country and Christian country music band. The band was founded in 1982 as an attraction for the Opryland USA theme park in Nashville, Tennessee, and was originally known as the Grizzly River Boys, then the Tennessee River Boys. It was founded by Matt Davenport, Danny Gregg, and Ty Herndon, the last of whom became a solo artist in the mid-1990s. After undergoing several membership changes in its initial years, the band has consisted of the same six members since 1989: Marty Roe (lead vocals, rhythm guitar), Gene Johnson (mandolin, guitar, fiddle, tenor vocals), Jimmy Olander (lead guitar, banjo), Brian Prout (drums), Dan Truman (keyboards), and Dana Williams (bass guitar, baritone vocals). After assuming the name Diamond Rio, the band was signed to Arista Nashville and debuted in 1991 with the single "Meet in the Middle", which made them the first band ever to send a debut single to No. 1 on the Billboard Hot Country Songs charts.
