Sonic Ceremony is a recurring party at House of Yes pairing DJ sets with a ritual-themed production concept, presented under the venue's House of Grooves series. This September 19 edition pairs Thessaloniki producer Echonomist, known for deep and melodic techno, with New York vocalist and producer OVEOUS, who blends soulful and Afro house with spoken word and live singing. Doors open at 10pm and the night runs until 4am the following morning. The event is 21 and up with no re-entry and no phones allowed on the dancefloor.
