Alvin Nathaniel Joiner (born September 18, 1974), better known by his stage name Xzibit (pronounced "exhibit"), is an American rapper, actor, songwriter, television host, and radio personality.

Xzibit began his musical career after the release of his debut studio album At The Speed Of Life on October 15, 1996. The album generated both critical and commercial success, peaking at number 74 on the Billboard 200. It also contained the single "Paparazzi", which peaked at number 83 on the Billboard Hot 100. This success allowed Xzibit to secure a recording contract with Loud Records later that year.

Xzibit released his second album 40 Dayz & 40 Nightz on August 25, 1998, which peaked at number 53 on the Billboard 200. The album also contained the single "What U See Is What U Get", which peaked at #50 on the Billboard Hot 100.

Restless debuted at number 14 on the Billboard 200, and was later certified platinum in the U.S. The album contained the singles "Front 2 Back", "X", and "Get Your Walk On". His follow-up album Man vs. Machine (2002) also enjoyed success; it debuted at number 3 on the Billboard 200 and was certified gold. Weapons of Mass Destruction (2004) also became certified gold. After the release of Full Circle in 2006, Xzibit underwent a hiatus, not releasing music until the release of his seventh studio album Napalm on October 9, 2012.
