Two people, one male and one female, are standing on a stage made of black speaker boxes. The male is wearing a red shirt and blue jeans, and the female is wearing a red shirt and brown pants. The male is holding a microphone. Both are looking toward the crowd. There are several people in the crowd behind the stage, mostly wearing red shirts. The stage is on a flatbed truck. The truck has a sign that says "Federasi Serbuk Indonesia, Berani Berjuang, Pasti Menang." There are flags hanging on the side of the truck that say "Indonesia." The scene takes place in front of a two-story white building, with many windows and a green roof. The building appears to have a sign on its front that says "Perkins." The sky is cloudy, and there is a metal pole with a speaker at the top. The scene appears to be in the city of Yogyakarta, Indonesia, near Jalan Sudirman and Jalan Malioboro, based on the coordinates provided.
