The Mad Cool festival has corrected the technical error that on Tuesday exposed the data of an indeterminate number of buyers to others who intended to access their subscriptions. The festival explained to EFE on Wednesday that, despite this, personal tickets for Mad Cool have not reached other people and that those that may have been downloaded are not valid.

The sixth edition of Mad Cool, which will be held from July 6 to 8 in Madrid, includes names such as Liam Gallagher, Robbie Williams, Sam Smith and Mumford & Sons.
