What were once drive-ins are now walk-ons. Berglund Center combined with Charlotte, North Carolina-based concert promoter MaxxMusic this spring to put on a series of drive-in shows on the venueâs parking lot. When soul-rocker Grace Potter hits the stage on Thursday for the third in the series, she will mark a change in the way theyâre done. No more drive-in shows from here on. The remaining events will be pod-style, socially distanced ones. The change came in part because of evolving COVID-19 regulations about gatherings, MaxxMusic president Gregg McCraw said. But audience â and potential audience â feedback about accessibility and ticket prices further drove home the need, McCraw said in a Tuesday phone call from Charlotte.
