Alice in Chains (often abbreviated as AIC) is an American rock band formed in Seattle in 1987. Since 2006, the band's lineup has comprised vocalist/guitarists Jerry Cantrell and William DuVall, bassist Mike Inez and drummer Sean Kinney. Vocalist Layne Staley and bassist Mike Starr are former members of the band. The band took its name from Staley's previous band, Alice N' Chains. Often associated with grunge music, Alice in Chains' sound and style is deeply rooted in heavy metal. The band is known for its distinctive vocal style, which often included the harmonized vocals between Staley and Cantrell (and later Cantrell and DuVall).
