Mad Cool

Mad Cool is a music festival held annually in Madrid, Spain, since 2016. It chiefly features pop, rock, and indie music, as well as various DJs and electronic music performers.

The 2016 and 2017 festivals took place in the Caja Mágica. The organization then moved the festival to an open-air space in Valdebebas. Peak attendance happened in the 2018 edition, with participants distributed along the three days of the festival (12–14 July), featuring a troubling first day due to agglomerations. In the 2020 edition, the daily maximum attendance was reduced to 60,000 by the organization, and the length was expanded to four full festival days.
