In Ace Frehley's book "No Regrets" he says that one of the big reasons he left KISS was because the show was getting so "produced". With all the lighting cues, pyro cues, etc , there was little or no room to improvise anymore and the gigs were identical from night to night.... He would find his mind wandering during the show since he didnt even need to think about the playing or the performance anymore.
