Born in Romeo, Michigan, Rock was a rapper and hip hop performer with 5 releases between 1990 and 1997, including a reissue and an EP. After signing a recording contract with Atlantic Records in 1998, he gained commercial success in the rap-rock genre behind the singles "Bawitdaba", "Cowboy" and "Only God Knows Why". After Devil Without a Cause's success in 2000, he released The History of Rock, a compilation of remixed and remastered versions of songs from previous albums as well as the hit rock single, "American Bad Ass".
Rock's follow-up records became more rock-, country-, and blues-oriented, starting with 2001's Cocky. His collaboration with Sheryl Crow on the song "Picture" was his first country hit and biggest pop hit in the US to date charting at No. 4 on the Hot 100. After 2003's Kid Rock and 2006's Live Trucker sales declined from the previous releases, he then released Rock n Roll Jesus in 2007. The album featured the song "All Summer Long", which charted at No. 1 in eight countries across Europe and Australia. In 2010, he released Born Free, which featured an eponymous song that became the political campaign theme of Mitt Romney, the Republican nominee for President of the United States in the 2012 election.
