Mad Cool Festival 2026 marks 10‑year anniversary in Madrid
The Mad Cool Festival returned to Madrid from July 8‑11, 2026 at the Iberdrola Music venue, celebrating its tenth edition. The four‑day event attracted up to 50,000 attendees per day and featured a diverse lineup spanning rock, pop, indie and electronic music.
Headliners included Foo Fighters, Florence + the Machine, Twenty One Pilots and Nick Cave & the Bad Seeds, alongside numerous other acts across five stages. Organisers noted logistical challenges such as limited mobile coverage within the venue, which complicated communication for festival‑goers moving between stages.
The festival highlighted Madrid’s growing reputation as a major European music destination, drawing audiences from across Spain and abroad.
