Killer (Deluxe Edition) introduces a newly remastered version of the original release, which peaked at #21 on the Billboard albums chart. Along with the singles “Under My Wheels” and “Be My Lover,” the record also includes “Yeah, Yeah, Yeah,” “Desperado,” and the prog-rock-inspired epic “Halo Of Flies.” The bonus material features alternate takes for “You Drive Me Nervous,” “Under My Wheels,” and “Dead Babies.”
 
The collection also gives fans an unreleased live recording of the band’s performance at Mar Y Sol Pop Festival in Puerto Rico on April 2, 1972. Recorded a few months before the band returned to the studio to make School’s Out, the show previews “Public Animal #9” from the upcoming album. The band played most of Killer during the concert, including “You Drive Me Nervous,” “Under My Wheels,” and “Halo Of Flies.” They also tapped the group’s 1971 album, Love It to Death, for live versions of “Is It My Body?,” “Long Way To Go,” and the smash hit “I’m Eighteen.”
