Relentless is the second album by American country music artist Jason Aldean. It was released on May 29, 2007 via Broken Bow Records. The album debuted at number four on the U.S. Billboard 200 and at number one on the Top Country Albums chart, selling about 98,000 copies in its first week. On October 4 of the same year, the album was certified gold by the RIAA. It was certified platinum in September 2012.
Relentless has produced three chart singles for Aldean on the Hot Country Songs charts. The lead-off single "Johnny Cash" (originally recorded by Tracy Byrd on his 2004 album Greatest Hits) and "Laughed Until We Cried" both reached No. 6 on that chart, and the title track reached No. 15 in late 2008.
Ken Tucker of Billboard gave a positive review, saying that "every cut features full, guitar-driven production". He considered "Johnny Cash", "Back in This Cigarette" and "I Break Everything I Touch" standout tracks.
