In 1983, Kiss began performing without makeup and costumes, thus marking the beginning of the band's "unmasked" era that would last for over a decade. The band experienced a commercial resurgence during this era, with the Platinum-certified album "Lick It Up" successfully introducing them to a new generation of fans, and its music videos received regular airplay on MTV. Eric Carr, who had replaced Criss in 1980, died in 1991 of heart cancer and was replaced by Eric Singer. In response to a wave of Kiss nostalgia in the mid-1990s, the original lineup re-united in 1996, which also saw the return of its makeup and stage costumes. The resulting Alive/Worldwide Tour was highly successful, grossing $143.7 million, making it the band's most successful tour to date. Criss and Frehley subsequently left the band again, and have been replaced by Singer and Tommy Thayer. The band has continued with its original stage makeup, with Singer and Thayer using the original Catman and Spaceman makeup, respectively. In September 2018, Kiss announced that, after 45 years of recording and performing, it would be embarking on its ongoing final tour, the End of the Road World Tour, which started in January 2019 and is currently set to conclude in 2022.
