The recent passing of Ace Frehley, the iconic “Spaceman” guitarist of KISS, has brought renewed attention to his storied and often turbulent relationship with the legendary band. Known for his electrifying stage presence and unique style, Frehley’s journey with KISS was marked by multiple departures, each fueled by underlying tensions and artistic disagreements.

Diving into the chronicles of KISS unveils a narrative filled with personality clashes, personal demons, and a rivalry that persisted over the years, lingering even after Frehley’s death.

Creative Differences Led To Ace Frehley’s Initial KISS Departure

Frehley’s initial exit from KISS in 1982 stemmed from a growing sense of creative discontent. As the band shifted from their signature 1970s rock sound to the more polished production typical of the 1980s, Frehley found himself increasingly at odds with the new direction. His involvement in the albums “Killers” and “Creatures of the Night” was minimal, as he was already contemplating a future beyond KISS. The success of his 1978 solo album, “Ace Frehley,” featuring the hit “New York Groove,” bolstered his confidence to pursue a solo career. Reflecting on this success, Frehley noted that it made him realize he was “more creative away from Paul, Gene, and Peter.” Despite Paul Stanley’s efforts to persuade him otherwise, Frehley chose to leave the band, asserting it was of his “own free will.”

Substance Abuse And Control Fueled the KISS Internal Feud

The narrative surrounding Frehley’s departures became a contentious issue. Gene Simmons and Paul Stanley have often claimed that Frehley was dismissed from KISS due to “drugs, alcohol, bad behavior, [and] being unprofessional.” Yet, Frehley has consistently refuted these allegations, maintaining that he resigned both times. He has accused Simmons and Stanley of being “control freaks” and “untrustworthy,” suggesting they cultivated a toxic work environment.

Frehley further claimed that Simmons’s public remarks about his past substance abuse negatively impacted his career, costing him millions even after achieving sobriety. The discord was mutual; Frehley also made serious accusations against Simmons, including an alleged incident where he claimed Simmons inappropriately touched his wife.

The KISS Guitarist Never Reconciled With Paul Stanley

Although Frehley suggested he had “buried the hatchet” with Gene Simmons, considering them “closest” and “just like brothers,” his relationship with Paul Stanley remained fractured. The tension escalated after a 2023 interview where Stanley remarked that the original KISS lineup sounded more like “Piss.”

A deeply insulted Frehley demanded an apology, to which Stanley reportedly responded with a profanity-laced refusal and hung up the phone. Frehley noted that prior to that clash, they would speak several times a year, but the incident left them estranged.

Bandmates Paid Tribute After The Rock Legend’s Passing

Following the announcement of Ace Frehley’s death on October 16, 2025, his former bandmates shared public tributes. Paul Stanley and Gene Simmons issued a joint statement saying they were “devastated” and acknowledging Frehley as “an essential and irreplaceable rock soldier” in KISS’s history and legacy.

I remember 1974 being in my room at the Hyatt on Sunset in LA and I heard someone playing deep and fiery guitar in the room next door. I thought “Boy, I wish THAT guy was in the band!” I looked over the balcony… He was. It was Ace. This is my favorite photo of us… pic.twitter.com/3ojMXqVkQr

Original drummer Peter Criss expressed his shock and grief, simply posting, “I’m shocked!!! My friend… I love you!” The rock world at large also mourned, with tributes from figures like Pearl Jam’s Mike McCready, who credited Frehley and KISS for inspiring him to pick up a guitar.

Ace Frehley’s Legacy As A KISS Founding Member Endures

Ace Frehley’s impact as a founding member of KISS is indelible. He co-created the band in 1973 and was the iconic “Spaceman” until his first departure in 1982, playing on the band’s first nine albums. His influence extended to generations of guitar players, with musicians like Tom Morello of Rage Against the Machine calling him his “first guitar hero.”

Despite the acrimony of his later years with the band, his former replacements, including Tommy Thayer and Bruce Kulick, paid their respects, with Thayer honoring the “legend who will never be forgotten” and Kulick affirming his “undeniable role in the creation and success of KISS.”
