Diamond Rio is an American country band which has transitioned to contemporary Christian music in recent years. The six members of Diamond Rio, Marty Roe, Dan Truman, Gene Johnson, Brian Prout, Jimmy Olander, and Dana Williams, found success with their “young country” sound, mixing country rock rhythms with bluegrass-inspired vocal harmonies and string arrangements. Diamond Rio's sound later evolved toward country-pop.
Many of the group's songs have positive or spiritual messages, including several of their biggest hits: “One More Day,” “I Believe,” and “Mama Don't Forget to Pray for Me.” All of the band members are Christians and wanted to express their faith more explicitly. In 2007 Diamond Rio signed with a Christian record label and released a Christian holiday album, A Diamond Rio Christmas: The Star Still Shines. The band continued their departure from traditional country with a contemporary Christian album, The Reason.
Diamond Rio became the first country artist ever to have a debut single hit No. 1 with “Meet in the Middle” in 1991. Since then, the band had recorded seven studio albums, 2 greatest hits collections, and a Christmas album. Diamond Rio and Love a Little Stronger are certified platinum albums. 32 Diamond Rio songs are charting singles, including “Norma Jean Riley,” “Love a Little Stronger,” “How Your Love Makes Me Feel,” and “Beautiful Mess.” The band has won six awards for Vocal Group of the Year from the Country Music Association and the Academy of Country Music. The band's members are also highly involved in philanthropic projects and received the Minnie Pearl Humanitarian Award in recognition of their work with Big Brothers Big Sisters of America and the American Lung Association. Diamond Rio made its Opry debut in 1991 and was inducted in 1998.
