Midsummer Night Polyphony Festival
Un concert dans le noir. rien à voir!
On Friday 20 June, FLOW Festival opens with an absolute bang: the groundbreaking concert by Dionysos Now! and Maxime Denuc. In Ostend’s majestic Peter and Paul Church, Renaissance polyphony and pulsating techno-dub from a midi-controlled church organ fuse into a hypnotic high mass of sound.
But that’s not all. Those who want will be given an eye mask and experience the concert completely in the dark. No visual stimuli, no distractions. Just you and the music. Pure focus. Pure flow.
Don’t want to miss this unique concert dans le noir? Order your tickets now before your eyes close!
