Exodus is an American thrash metal band formed in 1979 in Richmond, California. They have gone through numerous lineup changes, two extended hiatuses, and the deaths of two former band members. Their current lineup consists of guitarists Gary Holt and Lee Altus, bassist Jack Gibson, drummer Tom Hunting, and lead vocalist Steve "Zetro" Souza. Hunting is one of the original members, and departed from Exodus twice, in 1989 and 2004, but rejoined in 2007.
