On July 11th, Harmony Rec. returns to host an open air party at the glorious courtyard of the Czech National Library. The venue that is commonly known as Klementinum will turn into a safe space where ravers can finally gather after the long emergency break. To make the occasion even better, international producers like Blind Observatory, Shoal and Vand are coming by to perform. The lineup also consists of the Harmony residents: Alfred Czital, Yan and Raleigh. Limited capacity.
