On 15 August 2026, Sondaschule will bring their high-energy ska-punk show to the dramatic open-air setting of Festung Ehrenbreitstein in Koblenz, where the band's punchy horns, driving guitars, and singalong choruses will resonate against the centuries-old stone and overlook sweeping views of the Rhine and Moselle; the summer evening promises an electric atmosphere as fans gather on the fortress grounds to dance, shout and share the communal rush that defines a great live performance, while stage lights and festival production transform the historic ramparts into a vivid backdrop for an unforgettable concert experience, and patrons are encouraged to secure tickets early to ensure they don’t miss this unique night of music and panoramic scenery.
