Here’s a concise description of the video: The video shows a stage performance taking place outdoors at dusk, in front of a large audience. The stage is covered with a trussed canopy that has stage lights. On stage, performers wearing traditional Bulgarian costumes are dancing. Behind them, a large screen displays the text “150 години Априлско въстание,” which translates to “150 years of the April Uprising,” with flames projected on either side of the words. Three men are playing drums. The audience is visible in the foreground, their faces are mostly obscured by shadow.
