Wednesday evening — Waterfall Festival, but the forecast says rain

From 21:00, Waterfall Party — five stages, DJs Nata, Boyonic, Graham Gold, Bank Waterfall, Jordan Love, non-stop music. Entry with tickets. This is the organiser's announcement, we haven't checked it out yet.
It's an open-air festival, and from 21:00 to midnight the weather folks are expecting rain — better bring a raincoat. Or you'll be heading home soaked :|
