As of 2026, all four original founding members of KISS—Gene Simmons, Paul Stanley, Ace Frehley, and Peter Criss—are still alive. However, the statement that "all" members in the band's history are alive is factually incorrect. Two former official members, drummer Eric Carr and guitarist Mark St. John, passed away in 1991 and 2007, respectively.
KISS is one of the most iconic brands in rock history, known as much for their "larger than life" personas as their pyrotechnic-laden stage shows. Since their formation in New York City in 1973, the band has seen several lineup changes. While the "classic" lineup remains intact in the physical world, the passage of time has inevitably affected the full roster of musicians who have donned the greasepaint. Understanding the current status of these rock legends requires a look at both the original quartet and the talented musicians who stepped in during various eras of the band's half-century career.
The Original Founding Four: Where Are They Now?
The most common reason fans ask if all members are still alive pertains to the "Original Four." This lineup—consisting of the Demon, the Starchild, the Spaceman, and the Catman—defined the 1970s rock landscape. In 2026, these four men are in their 70s and early 80s, each pursuing different paths following the official conclusion of KISS's live touring career.
Gene Simmons (The Demon)
Gene Simmons, born Chaim Witz, remains a towering figure in both music and business. In 2026, Simmons continues to oversee the massive KISS merchandising empire. Having performed the final KISS "End of the Road" show in December 2023 at Madison Square Garden, Simmons has transitioned into a "post-touring" phase. While he no longer performs the physically demanding three-hour KISS sets in 40 pounds of armor, he remains active with his solo band and various entrepreneurial ventures. His health remains robust, a fact he often attributes to his lifelong avoidance of drugs and alcohol.
Paul Stanley (The Starchild)
Paul Stanley, the band's primary frontman and rhythm guitarist, is also very much alive and active in 2026. Following the retirement of the KISS live entity, Stanley has focused significantly on his passion for fine art. His paintings have become highly sought after by collectors, and he frequently hosts gallery openings across the United States. Stanley has also been open about his health journey, including his successful hip replacement surgeries and his management of microtia (a congenital ear deformity), proving that physical resilience is a hallmark of his later years.
Ace Frehley (The Spaceman)
The original lead guitarist, Ace Frehley, is alive and continues to release solo music. Frehley, who left the band twice (once in 1982 and again in 2002), has enjoyed a resurgence in his solo career over the last decade. In 2026, he remains a staple of the rock world, frequently appearing at conventions and performing club dates. Despite past struggles with substance abuse, Frehley has maintained long-term sobriety, which fans credit for his continued ability to perform his signature smoking-guitar solos well into his 70s.
Peter Criss (The Catman)
The original drummer, Peter Criss, is the oldest member of the founding four. In 2026, Criss lives a largely retired life, making occasional appearances at fan conventions like "KISS Expo." Criss is a male breast cancer survivor, having been diagnosed and successfully treated in 2008. His survival and subsequent advocacy have made him an inspirational figure in the rock community. While he has largely stepped away from the drum kit professionally, he remains a revered figure among the "KISS Army."
The Final Touring Lineup (2004–2023)
In addition to Simmons and Stanley, the final touring lineup of KISS featured two long-serving members who helped sustain the band's popularity for two decades. Both are active and well in 2026.
Eric Singer
Eric Singer took over the role of "The Catman" permanently after Peter Criss's final departure. Having played with the band across multiple stints since the early 1990s, Singer is widely regarded as one of the most technically proficient drummers in rock. In 2026, Singer continues to work as a session musician and a highly respected figure in the horology community (as an avid watch collector).
Tommy Thayer
Tommy Thayer, who donned the "Spaceman" makeup for over twenty years, is also alive. Thayer served as the band's lead guitarist from 2002 until their final show in late 2023. Since the band retired from the road, Thayer has shifted his focus toward his various business interests and his role in managing the legacy of the band’s production history.
Remembering the Members Who Have Passed Away
While the original lineup remains, the history of KISS is marked by the loss of two significant contributors. Any discussion of whether "all" members are still alive must acknowledge these two musicians.
Eric Carr (The Fox)
Eric Carr joined KISS in 1980 following the departure of Peter Criss. He chose the persona of "The Fox" and was a beloved member of the band during their "Unmasked" and "Lick It Up" eras. Carr was known for his heavy hitting style and his immense kindness toward fans.
Tragically, Carr was diagnosed with a rare form of heart cancer (atrial angiosarcoma) in early 1991. Despite aggressive treatment, he passed away on November 24, 1991, at the age of 41. His death occurred on the same day as Queen frontman Freddie Mercury, which often results in his passing being overshadowed in general music history, though KISS fans continue to hold annual vigils and tributes in his honor.
Mark St. John
Mark St. John was the band’s third lead guitarist, replacing Vinnie Vincent in 1984. He performed on the hit album Animalize. However, his time with the band was cut short by a sudden onset of reactive arthritis (Reiter's Syndrome), which caused his hands and arms to swell, making it impossible for him to play guitar at a professional level.
St. John eventually recovered enough to play in other projects, but he never returned to the global spotlight of KISS. He passed away on April 5, 2007, at the age of 51, following a brain hemorrhage. His contribution to the band’s "unmasked" era remains a significant part of the KISS timeline.
Living Former Members: The Non-Makeup Eras
Beyond the makeup-wearing members, two other guitarists played pivotal roles during the band's history and are still alive in 2026.
- Bruce Kulick: Bruce was the band's lead guitarist for the longest duration during their "no makeup" era (1984–1996). He is very active in 2026, frequently performing KISS hits with his own band and participating in "KISS Kruise" events. He is highly respected for his melodic playing and his role in keeping the band's musicianship high during the late 80s and early 90s.
- Vinnie Vincent (The Ankh Warrior): Vincent replaced Ace Frehley and co-wrote many of the songs on Creatures of the Night and Lick It Up. After disappearing from the public eye for decades, he re-emerged in recent years. In 2026, he continues to make sporadic appearances at fan events, though he remains a more reclusive and controversial figure in the band's lore.
Summary of KISS Member Status (2026)
The following table provides a clear breakdown of every official member of KISS, their years of service, and their current status as of 2026.

The "Digital" Future: Avatars and Immortality
One reason the question of KISS members' mortality has become a hot topic in 2026 is the band's transition into digital avatars. Following their final physical show in 2023, the band announced they would continue as digital performers, developed by Industrial Light & Magic (ILM) and Pophouse Entertainment.
This technology allows "KISS" to remain active forever, even after the physical members eventually pass away. This has created a unique situation where the "characters" of the Demon and Starchild are essentially immortal. However, it is vital for fans to distinguish between these digital entities and the living, breathing musicians who created the legacy.
