Ernest Clayton Clay 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.
A considerable legacy of Walkerâs violent writings is found in black abolitionist Henry Highland Garnet, who called for slave uprisings at the 1843 National Negro Convention in Buffalo, New York; and Frederick Douglas, who spoke in violent terms when discussing slavery with fellow black abolitionists.
