"I don't open for bands that I influenced," Roth reportedly told Sixx.
It's unclear when the communication took place — whether it was prior to the 'Stadium Tour' being announced in late-2019 or after the tour was postponed in the spring of 2020.
Roth's first solo gigs in years took place in Las Vegas in early-2020. He then played several shows with Kiss on the band's 'End of the Road' tour before the pandemic put a stop to everything.
When asked why Roth did not return to tour with Kiss this summer, Gene Simmons suggested that his performing career might be over. Roth has not explained his withdrawal from the Kiss tour, but his reaction to Simmons' comments prompted the bassist to profusely apologize.
