Once again Alice in Chains showed their collective greatness when they released this experimental EP in 1993. Sporting a versatility that shocked many listeners upon its release, Jar of Flies showed that good things could happen when a group is allowed to “just mess around” in the studio, provided that they have the chemistry and talent to make it work

Facelift was an ultra heavy and dark debut album with a brilliant beginning barrage. “We Die Young” “Man In The Box” became a signature song and the one that first got the band noticed. Next, “Sea Of Sorrow” surges along on a sing along chorus before the band gets more atmospheric for “Bleed The Freak” and “I Can’t Remember.”

Layne's drug addictions pretty much put an end to Alice In Chains, so Jerry Cantrell started a solo career and Columbia started emptying the vaults, including a 3-cd box set, Music Bank (1999), which contained loads of rarities for hardcore fans, and several unnecessary "greatest hits" albums.

Simply put, Sap proved that Alice in Chains were more than merely an exceptional heavy metal band. With vocal support from Ann Wilson of Heart, Chris Cornell of Soundgarden, and Mark Arm of Mudhoney, this EP turns down the amps from Facelift while still maintaining the band’s trademark intensity.
