Dirt is the second studio album by the American rock band Alice in Chains and was released on September 29, 1992, through Columbia Records. Peaking at number six on the Billboard 200, the album was well received by music critics and has since been certified four-times platinum by the RIAA and has gone on to sell 5 million copies worldwide, making Dirt the band's highest selling album to date. It was the last album to feature band's original line-up, as bassist Mike Starr would be dismissed due to his high drug abuse in 1993.
