Private Concert in the school ¡¡¡¡¡

The best Concert that I assisted was one to organized my school. The student center for the alliances of 2014 was amazing. They made a lot different activities and one of that was the concert.
They invited a band that was not so famous in this moment, the name of the band was "Villa Cariño". 
Honestly I don´t like the music but the atmosphere the band create was indescribable. 
The school prepared for the concert 2 pitches and they only allowed the high school  students to stay in the event. The concert was so good that students from other school come to saw what happened.  
When the student center saw all this people out of the school They decided to open the gate  and let the people in. I danced with people that I never saw in my life but I didn´t care in that moment. The concert had a duration for 2 hours. When the concert finish all the people that was there cleaned the place. But the principal of school was not happy with idea that open the gate so He denied authorization for events.
