Keep it low‑key and predictable. Grab a small stage, lock the pier to prevent folks from wandering off, and set up a clear exit. Get a permit or at least the local park office a heads‑up. Use a reliable sound system and have a backup power source. Stick to a tight setlist, no surprise crowd‑sourcing or wild stunts. If you’re watching the crowd, make sure nobody can get stuck in the water or on the railing. That’s the chaos you can control; the rest is just noise.
