A string quartet is performing on stage in front of a seated audience. The quartet consists of three violinists and one percussionist. All performers are dressed in black. The percussionist is seated, playing a cajón. The violinists are standing, reading sheet music on stands. Behind the performers is a screen displaying the title "XXIV CONGRESO DE ARQUITECTURA" and other graphics. Several people in the audience are visible in the foreground, including one person with a camera who briefly obstructs the view of the stage. The stage appears to be made of wood.
