Dirt is the second studio album by American rock band Alice in Chains, released on September 29, 1992, by Columbia Records. It was the band's last album recorded with all four original members. The majority of the songs were written by guitarist Jerry Cantrell, but for the first time, vocalist Layne Staley wrote two songs by himself ("Hate to Feel" and "Angry Chair"), both also featuring Staley on guitar. The track "Iron Gland" features Tom Araya from Slayer on vocals. The album's lyrics explore depression, pain, anger, anti-social behavior, relationships, drug (primarily heroin) addiction, war, death, and other emotionally charged topics. ATTENTION: please remember that all Blu-Rays are Region A USA and all DVDs Region 1 USA and you will need a multi region Blu-Ray/DVD player to play them.
