3LSF (3-Country-City Festival)

12 + 13 June 2026

Featuring headliners Loi and Gallowstreet

Many people know the hits by Mannheim-based artist Loi from TV or the radio. Her music has been streamed millions of times online. On June 13, she will headline this year’s 3LSF.

Right before her, Dikanda from Poland will take the stage, blending world music, Balkan influences, and folk in a unique way.

On June 12, Riserva Moac from Italy will kick things off on the main stage, before headliners Gallowstreet from the Netherlands get the crowd moving with a danceable mix of electronic music and brass.

On both days, local favorites Stadtmusik Weil am Rhein and Bonds Big Band will once again open the evening on Rathausplatz.

Marching Bands

And, of course, renowned marching bands will once again be performing on Sparkassenplatz and the Club Mile. This year, we’ve secured Spalehill Brass Band from Basel, Heart Attack Horns from Weil am Rhein, Improvisante from Switzerland, Ça Gaze from France, and Castle Groove Festival Brass Band from Germany to perform at 3LSF.

While the marching bands are performing on the Club Mile, Bonds Festival Combo and Chnopfi-Band will be playing on Sparkassenplatz.

Club Mile

Along the Club Mile, which stretches from Rathausplatz to Sparkassenplatz, groups will be offering delicious food and drinks for sale out of more than 20 huts.

Free admission

Great bands and free admission — that’s what makes 3LSF so special. No registration is required. Just stop by and enjoy the music, the atmosphere, and the delicious food at our Club Mile!
