The 2020 festival was to begin Wednesday in Madrid. This year's event was canceled in May due to the coronavirus (COVID-19) pandemic.
"During all these weeks, and considering the course of events, we have been working on different scenarios. The most real and practical one is to move the festival to 2021," organizers said.
"It has not been an easy decision to make, but we believe is the best one considering the present circumstances," organizers added. "Your health and safety are our priorities."
Other international music festivals have also been postponed to 2021 due to the health crisis. The Strokes and Tyler, the Creator will headline Primavera Sound Barcelona in July 2021.
