Alice in Chains is an American rock band formed in Seattle, Washington, in 1987 by guitarist Jerry Cantrell and vocalist Layne Staley. Although widely associated with grunge music, the band's sound incorporates heavy metal and acoustic elements. Since its formation, Alice in Chains has released four studio albums, three EPs, two live albums, four compilations, and two DVDs. The band is known for its distinct vocal style which often included the harmonized vocals of Staley and Cantrell.
Although never officially disbanding, Alice in Chains was plagued by extended inactivity due to substance abuse, culminating in the death of Layne Staley in 2002. Alice in Chains reunited in 2005 with new lead vocalist William DuVall and released Black Gives Way to Blue, their first studio album in 14 years, on September 29, 2009.
