Kiss’s next four concerts have been postponed because Gene Simmons has tested positive for COVID-19, just five days after the band had to cancel a show because Paul Stanley had tested positive.

The band made the announcement Tuesday, saying that the musicians and crew members will have to stay at home and self-isolate for the next 10 days. Simmons’ symptoms are said to be mild, and Kiss’s tour is set to start up again on September 9 at the FivePoint Amphitheatre in Irvine, Calif.
