StadtSommerKassel – Open Air Hessenkampfbahn (Jazeek & Johannes Oerding)

In the summer of 2025, the City of Kassel once again hosted a series of major open-air concerts at the Karlswiese. As in previous years, the organizer was MM Konzerte GmbH, who brought several top acts from the German pop and rock scene to the stage in close coordination with the City of Kassel. The Karlswiese has established itself as a central venue for Kassel's Stadtsommer.
