Alice in Chains is an American rock band formed in Seattle, Washington, in 1987 by guitarist Jerry Cantrell and original lead 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.
Alice in Chains rose to international fame as part of the grunge movement of the early 1990s, along with other Seattle bands such as Nirvana, Pearl Jam and Soundgarden. The band was one of the most successful music acts of the 1990s, selling over 25 million albums worldwide, and over 12 million in the US alone. The band achieved two number-one Billboard 200 albums (Jar of Flies and Alice in Chains), 14 top ten songs on the Mainstream Rock Tracks chart, and eight Grammy Award nominations.
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.
