Alice N' Chains was an American glam metal band from Seattle, Washington formed in 1986 by former members of Sleze.
 Towards the end of their run as Sleze, discussions arose about changing their name to "Alice in Chains".
 However, due to concerns over the reference to female bondage, the group ultimately chose to spell it as Alice N' Chains.
 They performed under this moniker over about a 12-month period and recorded two demos before breaking up on friendly terms in 1987.
 One of its members, Layne Staley, ultimately took the name that he and his former bandmates had initially flirted with when he joined a different group a few months later that ultimately became known as Alice in Chains.
Layne Staley: Angry Chair is a biography by Adriana Rubio about Layne Staley, the lead vocalist of the rock band Alice in Chains, published in January 2003.
 As it is known, the book "Layne Staley: Angry Chair — A Look Inside the Heart and Soul of an Incredible Musician" written by Adriana Rubio (Argentinean journalist and a fan of Alice in Chains), features 50 pages of photos of Staley's art work, sketches, diary entries, and childhood pictures.
 It also contains an alleged last interview of Staley that Rubio claimed that she conducted less than three months before he died from an overdose of heroin and cocaine, in April 2002.
 Rubio did extensive interviews with Staley's mother, Nancy Layne McCallum, and his sister, Liz (née Elmer) Coats, to write the book.
 It is named after Alice in Chains' famous song, "Angry Chair".
William Bradley DuVall (born September 6, 1967) is an American musician, best known as being the current co-vocalist and a rhythm guitarist for the alternative metal band Alice in Chains replacing original vocalist Layne Staley, who died in 2002.
 DuVall joined Alice in Chains in 2006, and he appears on the 2009 album "Black Gives Way to Blue" as well as the 2013 follow-up "The Devil Put Dinosaurs Here".
