Reunion (1996–2002)

With that statement on February 28, 1996, Tupac Shakur introduced the original Kiss lineup (in full makeup and Love Gun-era stage outfits), to a rousing ovation at the 38th Annual Grammy Awards. On April 16, the band held a press conference aboard the USS Intrepid in New York, where they announced their plans for a full-fledged reunion tour, with the help of new manager Doc McGhee. The conference, emceed by Conan O'Brien, was simulcast to 58 countries. On April 20, nearly 40,000 tickets for the tour's first show sold out in 47 minutes.

The first public concert featuring the newly reunited Kiss was an hour-long warm up show on June 15 for the annual KROQ Weenie Roast in Irvine, CA, during which the band nearly ignited the stage of the Irvine Meadows Amphitheatre. On June 28, the Kiss Alive/Worldwide Tour began at Tiger Stadium in Detroit, Michigan in front of a sold-out crowd of 39,867 fans. The tour lasted for 192 shows over eleven months and earned $43.6 million, making Kiss the top-drawing concert act of 1996. The average attendance of 13,737 is the highest in the group's history.

In September 1998, the reunited group issued Psycho Circus. Despite its appearance as the first album with the original lineup since 1977's Love Gun, the contributions of Frehley and Criss were minimal. While the images of Frehley and Criss are featured prominently on the album, most of the lead guitar work was later revealed to have been performed by future band member Tommy Thayer and former member Bruce Kulick. Most drum duties were handled by session musician Kevin Valentine. Despite the controversy, the album achieved a #3 chart debut, the highest ever position for a Kiss album. The title track received a Grammy nomination for Best Hard Rock Performance. The Psycho Circus Tour opened at Dodger Stadium in Los Angeles, California on Halloween night 1998, and was simulcast on FM radio across the U.S. It proved to be another success, and was historic for being the first to ever incorporate 3-D visuals into a stage show.

On August 11, 1999, Kiss was inducted into the Hollywood Walk of Fame, in the Recording Industry category. August 13 saw the nationwide premiere of a Kiss-themed motion picture, titled Detroit Rock City. The movie takes place in 1978, and focuses on four teenagers (featuring Edward Furlong) willing to do anything to score tickets for a sold-out Kiss show in Detroit.

The next month, the group worked in collaboration with World Championship Wrestling to produce a Kiss-themed wrestler known as The Kiss Demon whose face was painted to resemble Simmons. The group performed God of Thunder live on WCW Monday Nitro to debut the character. The band got $500,000 for the one-night, one-song performance. The character was short-lived, as all ties to Kiss were cut by WCW when its head, Eric Bischoff was relieved of his duties in September of that year.

Kiss announced in early 2000 that they would be launching a U.S. Farewell Tour in the summer, which was to be the band's last. The group quickly added dates to the tour, which ran through April 2001. 2001 also saw the release of a computer game, Kiss: Psycho Circus: The Nightmare Child.

On the eve of the Japanese and Australian leg of the Farewell tour in early 2001, Criss suddenly left the band once again, reportedly unhappy with his salary. Taking his place was previous Kiss drummer Singer who, in a controversial move among longtime fans, assumed Criss's Cat Man persona as the Farewell Tour continued. Simmons and Stanley own Criss's makeup designs (as well as Frehley's), so there was no way for Criss to prevent this.

With the band scheduled to call it a day supposedly by early 2001, a career-encompassing collection entitled The Box Set (94 tracks on five CDs) was released in November of that year, while the summer saw perhaps the most outrageous item of Kiss merchandise yet – the Kiss Kasket. In introducing the Kiss Kasket, Simmons quipped, I love livin', but this makes the alternative look pretty damn good.

Kiss was relatively quiet through the rest of the year, but 2002 started with some controversy as Simmons took part in a controversial interview on National Public Radio, where he criticized NPR and berated host Terry Gross with sexual comments and condescending answers. In February 2002, Kiss (with Singer on drums and Frehley on lead guitar) performed during the Closing Ceremonies of the 2002 Winter Olympics in Salt Lake City, Utah. This was Frehley's last performance with Kiss to date.

On March 6, 2002, Kiss performed a private concert at a resort in Trelawny, Jamaica. Frehley, who was no longer under contract, did not play with the group. He was replaced by Tommy Thayer, who donned Frehley's Spaceman makeup and costume for his first live appearance with Kiss. That month, the band (with Thayer) taped an appearance on the American sitcom That '70s Show. The episode, That '70s Kiss Show, aired in August 2002. Thayer again performed with the group in April 2002, when Kiss performed Detroit Rock City (with pre-recorded music and live vocals) for an appearance on Dick Clark's American Bandstand 50th Anniversary show, which aired on May 3.
