Alice in Chains is an American rock band formed in Seattle, Washington, in 1987 by guitarist/vocalist Jerry Cantrell and drummer Sean Kinney, who then recruited bassist Mike Starr and lead vocalist Layne Staley. Mike Starr was replaced in 1993 by Mike Inez. The band took its name from Staley's previous group, the glam metal band Alice N' Chains. Although widely associated with grunge music, the band's sound incorporates heavy metal elements.

Following Alice in Chains' extensive 1993 world tour, Staley said the band "just wanted to go into the studio for a few days with our acoustic guitars and see what happened". "We never really planned on the music we made at that time to be released. But the record label heard it and they really liked it. For us, it was just the experience of four guys getting together in the studio and making some music." Columbia Records released Alice in Chains' second acoustic-based EP, Jar of Flies, on January 25, 1994. Written and recorded in one week, Jar of Flies debuted at number one on the Billboard 200, becoming the first EP--and first Alice in Chains release--to top the charts. Paul Evans of Rolling Stone called the EP "darkly gorgeous", and Steve Huey said, "'Jar of Flies' is a low-key stunner, achingly gorgeous and harrowingly sorrowful all at once". Jar of Flies features Alice in Chains' first number-one single on the Mainstream Rock charts, "No Excuses". The second single, "I Stay Away", reached number ten on the Mainstream rock charts, while the final single "Don't Follow", reached number 25. Jar of Flies has been certified triple platinum by the RIAA, with over 2 million copies sold in the United States during its first year. After the release of Jar of Flies, Staley entered rehab for heroin addiction. The band was scheduled to tour during the summer of 1994 with Metallica, Suicidal Tendencies, Danzig, and Fight, as well as a slot during Woodstock '94, but while in rehearsal for the tour, Staley began using heroin again. Staley's condition prompted the other band members to cancel all scheduled dates one day before the start of the tour, putting the band on hiatus. Alice in Chains was replaced by Candlebox on the tour. Susan Silver's management office sent out a statement saying that the decision to withdraw from the Metallica tour and Woodstock was "due to health problems within the band." The band broke up for six months. Kinney told Rolling Stone in 1996, "Nobody was being honest with each other back then. If we had kept going, there was a good chance we would have self-destructed on the road, and we definitely didn't want that to happen in public."
