Many exciting music festivals are usually held during the summer holidays.
In Spain, a sudden gust of wind struck and turned it into a nightmare scene.
A mix of thumping music and people screaming is the site of Spain's electronic music festival, the Medusa Festival.
The sand is fluttering and tents and furniture are flying around.
Day and night, while ripening with the heat of the performance, a gust of wind at 22 meters per second suddenly struck at dawn.
The audience fled from confusion, but a part of the stage collapsed, killing one person and injuring 40 others.
At that time, 50,000 spectators were enjoying the festival, so it took 40 minutes to evacuate.
The organizers have canceled all remaining festival schedules for safety reasons.
