Recent performers Opening headliners Winterfest Beginning in the winter of 1989–1990, Summerfest organizers staged an alternate version of Summerfest, known as Winterfest. Rather than being chiefly set at Henry Maier Festival Park, the event took inspiration from Summerfest's early days and spread its music, comedy, and other events throughout several downtown Milwaukee locations, the central spot being an ice skating rink in Cathedral Square Park. Due largely to undesirable Milwaukee winters, Winterfest was never as profitable as its older summer counterpart, and ceased operations after the 1997-98 event.
