A close up of a sign with graffiti on it in a building

Use a photograph or illustration of a stage in a dark, urban environment to create an underground effect. Use a palette of dark colors or shades of gray to reflect the atmosphere of the underground environment. Add graphic elements such as graffiti, stickers and urban elements to create an authentic atmosphere. Use bold typography, with street style, to emphasize the title of the event and create an eye-catching effect. Include short, direct messages that reinforce the theme of the event, such as "Rap in Mexico!" or "The true underground culture!" Use a textured and layered design to create a sense of depth in the flyer and give it a more authentic effect.
