Steven Adler's 20th anniversary celebration for Guns N' Roses debut album, Appetite for Destruction, threw down over the weekend on Saturday, July 28.

Izzy Stradlin, Duff McKagan and Slash joined Adler at the Key Club in West Hollywood. Unfortunately, something came up that forced Slash to cut out before the group could jam together. Izzy, Duff and Steven still obliged.

As previously predicted, Axl was a no-show.
