A total of 100 artists will intervene live on nearly a hundred premises, facades, and shutters provided by residents and merchants, turning the neighborhood into an ephemeral gallery. The creators were selected from over 500 proposals and come from various parts of Spain and countries such as Italy, France, Germany, Sweden, Brazil, and China, reinforcing the international character of the event.

For approximately twelve hours, participants will create their works live and compete for several cash prizes awarded by an independent jury. Additionally, the public will have the opportunity to recognize their work through popular vote.

As a notable new feature this year, the festival includes a venue at the Museum of History of Madrid, located on Fuencarral Street. The Plaza del Dos de Mayo will once again be one of the event's central hubs, offering information and various activities.

The festival's program began the day before with a young talent competition, focusing on artistic interventions on shop windows and doors in the neighborhood, thus extending participation beyond the main day. The event, organized by Madrid Street Art Project and the local media outlet Somos Malasaña, aims to promote accessible and participatory art while boosting the commercial and cultural activity of the area. It also has the support of the Madrid City Council and various collaborating entities.
