BELGRADE, SERBIA. A door guard objects to photos as young women wait to enter River, a club on a splav, or barge, on the Sava River ahead of a concert by Jelena Karleusa on the night of July 3, 2015. The splavs along the Sava and Danube Rivers are the epicenter of Belgrade's raging all night club scene; Karleusa is one of two of the turbofolk industry's greatest stars and certainly its most outspoken liberal voice and advocate for the gay community.
