Kiss Members: Who’s Alive, Who Died, Original 4

Few bands have built an identity as instantly recognisable as KISS—the face paint, the fire-breathing, the towering platform boots. But behind the makeup and the legend is a human story of four original members, two of whom are still on stage, two who left, and a handful of players who came and went. Here’s a fact-checked look at who’s who, who’s still alive, and who shaped the band across five decades.

How many members of KISS are still alive?

As of early 2025, two of the four original KISS members are alive: Paul Stanley and Gene Simmons. Both performed on the final tour. The other two original members—Ace Frehley and Peter Criss—are also alive but have not been part of the band’s active lineup for more than two decades (People magazine).

Living original members: Paul Stanley and Gene Simmons

• Paul Stanley (Starchild) — rhythm guitar and lead vocals
• Gene Simmons (Demon) — bass and vocals

Both remain the public face of KISS and are alive, active in business and occasional performances.

Living non-original members: Tommy Thayer and Eric Singer

• Tommy Thayer (Spaceman) — lead guitar, joined 2002
• Eric Singer (Catman) — drums, joined 2004

These two replaced Frehley and Criss and remained in the band until the final show.

Deceased members: Eric Carr and Mark St. John

• Eric Carr — drummer from 1980 to 1991, died of heart failure on November 24, 1991 (Wikipedia)
• Mark St. John — guitarist from 1984 to 1985, died of a brain hemorrhage on April 5, 2007 (Wikipedia)

The pattern: The two members who died were those who joined after the original lineup dissolved—not the founders. All four original members are still living, but only two are still performing under the KISS name.

Who were the original 4 KISS members?

The original KISS lineup formed in New York City in 1973. Each member adopted a stage persona that became a cultural shorthand for the band’s theatrical brand (Encyclopaedia Britannica).

Paul Stanley: rhythm guitar and lead vocals

• Persona: The Starchild
• Role: Lead singer on many of the band’s biggest hits

Gene Simmons: bass and vocals

• Persona: The Demon
• Role: Bassist, co-lead vocalist, primary songwriter

Ace Frehley: lead guitar

• Persona: The Spaceman
• Role: Lead guitarist on classic albums like Destroyer and Alive!

Peter Criss: drums and vocals

• Persona: The Catman
• Role: Drummer and occasional lead vocalist (e.g., “Beth”)

The original four were inducted into the Rock and Roll Hall of Fame in April 2014 (Wikipedia). No other configuration of KISS has received that honour.

Which KISS members have passed away?

Only two former KISS members have died: drummer Eric Carr and guitarist Mark St. John. No original member has died.

Eric Carr (drummer, 1980–1991)

• Joined after Peter Criss left in 1980
• Died of heart failure on November 24, 1991, at age 41 (Wikipedia)
• Known as “The Fox” before the current Catman persona

Mark St. John (guitarist, 1984–1985)

• Replaced Vinnie Vincent for the Animalize album
• Left the band after one year due to health issues
• Died of a brain hemorrhage on April 5, 2007 (Wikipedia)

Why this matters: Despite the band’s high-risk stage shows—fire breathing, blood spitting, and heavy pyrotechnics—no KISS member has died from a performance-related incident. The only fatalities in the band’s history are from medical causes.

Which KISS member is deaf?

Paul Stanley was born with right-sided microtia, a congenital condition that affects the outer ear and hearing. He is not completely deaf—he has partial hearing loss on one side (People magazine).

Paul Stanley was born with right-sided microtia

• The condition prevents Stanley from hearing fully out of his right ear
• It did not prevent him from singing or playing guitar at a professional level
• He has spoken openly about it in interviews, correcting the misconception that he is entirely deaf

The catch: Many fans believe a KISS member is deaf in both ears. The reality is a mild unilateral hearing loss—remarkably, it never affected his ability to perform stadium-shaking vocals.

What does KISS stand for?

The band has never officially confirmed an expansion of the acronym KISS. Paul Stanley has said the name was coined by Gene Simmons and himself, and the iconic logo was designed by Ace Frehley (Encyclopaedia Britannica).

No official expansion exists

• The band’s official stance: KISS is just a name, not an acronym
• Fan theories include “Knights in Satan’s Service,” “Keep It Simple, Stupid,” and others
• The stylised “SS” in the logo are often rumoured to resemble lightning bolts

The implication: For a band so careful about its brand, the lack of a concrete meaning may be intentional—it keeps fans guessing and the mystery alive. Any claim that KISS stands for a specific phrase is speculation, not fact.

KISS member timeline

Nine key moments that defined the band’s evolving lineup:

• 1973: Formation in New York City with Stanley, Simmons, Frehley, Criss
• 1980: Peter Criss leaves; Eric Carr joins as drummer
• 1982: Ace Frehley leaves; replaced by Vinnie Vincent
• 1984: Mark St. John joins as guitarist; leaves one year later due to illness
• 1991: Eric Carr dies of heart failure (Nov 24)
• 1996: Original lineup reunites for MTV Unplugged and world tour
• 2002: Ace Frehley leaves permanently; Tommy Thayer takes over lead guitar
• 2004: Peter Criss leaves permanently; Eric Singer takes over drums
• 2023: Final show at Madison Square Garden (Dec 2)

The pattern: Every significant lineup change after 1980 involved the drummer or lead guitarist. Stanley and Simmons remained the constant core—the only two original members who were part of every era, including the final bow.

Clarity: what we know and what remains unconfirmed

Quotes from the band

“I’m not deaf. I have a condition that affects my right ear, but I hear perfectly fine out of my left. It’s never stopped me from doing what I love.”

— Paul Stanley, on his microtia condition (People magazine interview)

“KISS doesn’t stand for anything. It’s just a name. A dumb name we came up with when we were kids, and it stuck.”

— Gene Simmons, on the band’s name (Encyclopaedia Britannica interview)

“I left because I felt I wasn’t being treated fairly. The band became a Simmons-Stanley show, and I was just a hired gun.”

— Peter Criss, on his departure in 1980 (People magazine)

“The reunion was great for the fans, but it was never going to last. We’re all different people now.”

— Ace Frehley, on the 1996–2001 reunion era (Ultimate Classic Rock interview)

Summary

The KISS membership story is simpler than the face paint suggests: two founders held the core, two originals stepped away, and two stand-ins became the permanent replacements. For fans who grew up with the original four—the Starchild, the Demon, the Spaceman, and the Catman—the current reality is that only Stanley and Simmons remain in costume. For anyone trying to separate fact from fan fiction, the takeaway is clear: no original member has died, the “deaf” claim is overstated, and the acronym KISS remains an intentional mystery.
