The 2026 edition of Primavera Sound attracted around 287,000 attendees and proved to be more eventful than anyone expected. From perilous weather conditions to surprise artists joining the lineup, this year's festival may have produced more surprises than any recent installment.
Perhaps the biggest surprise came from Olivia Rodrigo, who was not listed on the official lineup but appeared in Barcelona for an unexpected concert announced only hours before taking the stage. The pop superstar delivered an 11-song set that immediately became one of the most talked-about moments of the festival. Her set came days before the release of her new album, "you seem pretty sad for a girl so in love."
