Kulick initially tried out for KISS back in 1972, when it was still an unknown band, but Ace Frehley ended up snagging the guitarist gig instead. Five years later, KISS brought on Kulick for the record “KISS Alive II,” and he secretly recorded for them. From there, he secretly recorded more albums with KISS, including, “Unmasked,” “Killers” and “Creatures of the Night.”

Kulick said in 2018 that he had no problem keeping his work with KISS a secret.

“In this circumstance, being friends with Gene [Simmons] and Paul [Stanley], it was important to me that when they said ‘This has to be between us and us only,’ that I’m going to keep my word,” he said. “It’s all about integrity, and that’s how I’m able to keep going.”

“I make great music; I don’t settle,” Kulick continued. “I never went for the easy way: ‘Oh, just take the money.’ I never did that, it’s just not me. I never recorded an artist and took their money if I thought they were below the bar line, like ‘this is going to be embarrassing.’ It wouldn’t help them, it wouldn’t help me.”
