Diamond Rio

Diamond Rio is a country & Christian music band that was formed in 1982 as an attraction for the Nashville, Tennessee, Opryland USA theme park.

Originally known as the Grizzly River Boys, then the Tennessee River Boys, Diamond Rio went through several personnel changes in its first few years, but the lineup has stayed the same 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. The band charted 32 more singles between then and 2006, including four more that reached No. 1: "How Your Love Makes Me Feel" (1997), "One More Day" (2001), "Beautiful Mess" (2002), and "I Believe" (2003).

The Grammy Award-winning band is known for its vocal harmonies, varied instrumentation, and near-exclusive use of only its own membership on recordings instead of session musicians. Their sound was originally defined by mainstream country, bluegrass, and rock influences, but later albums drew more influence from Christian country music and country-pop.
