<human>: Ernest Clayton Walker, Jr. (born August 19, 1969) is an American country music artist. He made his debut in 1993 with the single "What's It to You", which reached Number One on the Billboard Hot Country Singles & Tracks (now Hot Country Songs) chart, as did its follow-up, 1994's "Live Until I Die". Both singles were included on his self-titled debut album, released in 1993 via Giant Records. He stayed with the label until its 2001 closure, later recording for Warner Bros. Records and RCA Records before joining his current label, Asylum-Curb Records, in 2007.

Walker released his twenty-third single, "Say No More", for Giant in early 2001. It was the first single release from his sixth studio album of the same name, peaking at number 33 on the country chart; the only other single, the Jerry Kilgore co-write "If You Ever Feel Like Lovin' Me Again", reached number 27. The latter song was promoted by Giant's parent company, Warner Bros. Records Nashville, as Giant had closed in late 2001. Walker co-produced the album with veteran producers Byron Gallimore and Blake Mevis, and session guitarist Brent Mason. The album also included a song that Walker wrote in high school, and a cover of Ritchie Valens's "La Bamba." Maria Konicki Dinoia of Allmusic rated it three stars, with her review saying that "the sensitivity on this album is so expressive that it makes you want to run right out and hug the one you love." Country Standard Time critic Mike Clark considered it a transition to a more country pop-oriented sound, describing the album as being "full of bad lyrics and overwrought production cliches."  In 2002, Walker wrote and recorded a song for the National Football League's expansion team, the Houston Texans. Titled "Football Time in Houston," the song was used as the team's official fight song during its inaugural season. In an interview with CMT, he said that he donated the song to the city of Houston, and that he sings "The Star-Spangled Banner" at the team's opening game every season.  Although he had left Warner Bros. for RCA Records' Nashville division in May 2002, Warner Bros. released a Christmas music album entitled Christmas in September of the same year. It included a cover of Jose Feliciano's "Feliz Navidad", which Walker took to number 49 on the country chart in January 2003.
