Live Jam — Open Air
Participatory live music in the sun. The day starts loose, warm, and open.
A mini festival

Summer Jam doesn't start with a headline. It starts with a live jam in the sun: open, participatory, warm. People finding the rhythm together before a single DJ has touched the decks.
From there the energy builds. Live music gives way to DJ sets. The dancefloor opens gradually as afternoon moves toward evening.
When the garden closes at 23:00, the night doesn't stop. The party continues indoors till late: a natural extension of a day that has been building since the first note.
No big headline, no manufactured hype. Just a full day that earns its dancefloor.
