(WKBW) â After more than a year, it's lights up at the Riviera Theatre once again. "We're going to target June 25th to get concerts rolling here again," Executive Director David Fillenwarth said. According to Fillenwarth, the plan for the venue's first concert since march of 2020 is for 100% capacity. They have been selling tickets to accommodate despite current restrictions being unclear. "I know it's going to change again," Fillenwarth said, "I think we will take a look at this a couple weeks down the road. From my understanding if you have been vaccinated you should be able to enter to see a show."
