"What we had at the beginning was magical, not because we were virtuosos... Ace and I played great together. But in my mind, it's a crime what Ace did. He threw away incredible potential and talent. The Ace I played with when the band first started out was a comet... But he stopped practising. He got involved with a whole lot of things that really diluted and diminished his craft. I saw that comet grow dim." KISS frontman Paul Stanley takes aim at the band's former guitarist Ace Frehley.
