Jar of Flies
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.
While never originally intended for a public release, 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 ever EP—and first Alice in Chains release—to top the charts. Paul Evans of Rolling Stone called the EP "darkly gorgeous",  Jar of Flies features Alice in Chains' only number one single on the Mainstream Rock charts, "No Excuses". The second single, "I Stay Away", reached number ten on the Mainstream rock charts . After the release of Sap, Layne Staley entered rehab for heroin addiction. The band was scheduled to tour during the summer of 1994 with Metallica and Suicidal Tendencies, 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.
After a decade battling drug addiction, Layne Staley was found dead in his condominium on April 19, 2002. An autopsy revealed Staley died from a mixture of heroin and cocaine 14 days previously. 9]
