KISS had to briefly stop their recent concert in Manaus, Brazil this past Wednesday (April 12) after Gene Simmons became ill

The concert marked the opening show of the Brazilian leg of KISS‘s “End Of The Road” farewell tour, which also features SCORPIONS and SEPULTURA as special guests.

Brazilian news website G1 reported that Gene had asked at one point during the show for a member of the road crew to bring him a chair which he ended up using for the remainder of the concert.

Before KISS took a short break during the concert, frontman Paul Stanley told the crowd: “We’re gonna have to stop to take care of him, ’cause we love him, right? Let’s give Gene a really loud ‘Gene‘.” He then added that he and his bandmates would return to the stage “a little bit later.”

Brazilian journalist Igor Miranda reported that the band returned to the stage five minutes later, with Gene greeting the audience in Portuguese, saying: “Manaus, all right!”, adding “Thank you.”

Speculation has run high as to the cause of Gene feeling unwell, with the majority of opinions leaning toward heat exhaustion as being the culprit. According to the National Institute of Meteorology (INMET), the temperature in Manaus at the time of the concert was between 26.9 degrees Celsius (80.4 degrees Fahrenheit) and 27 degrees Celsius (80.6 degrees Fahrenheit).

KISS‘s “End Of The Road” was originally scheduled to wrap up on July 17, 2021 in New York City but has since been extended to late 2023.
