During Summerfest, the 75 acre (30 ha) park hosts the industry’s biggest acts for an unforgettable live music experience, from late June until early July (including the Fourth of July). It was announced in 2021 that the festival would move to a three weekend schedule to allow for more Friday and Saturday event days. The performers include local and nationally known music talent from various genres, performing throughout the grounds from noon to midnight, including the 23,000-capacity American Family Insurance Amphitheater. Since 2004, nearly $150 million has been invested into Henry Maier Festival Park, including permanent stages, bars, production space, VIP amenities and other infrastructure.
