This video shows part of that 19 December gig, in concert hall Gebroeders De Nobel in Leiden. Various people in the audience start crowd surfing. At about 0:45, the Muslim girl starts.
Translated from Vincent Frequin at Dichtbij.nl in the Netherlands, 22 December 2015:
LEIDEN – The photo of a Muslim girl crowd surfing at a concert in Leiden goes all over the internet. Photographer Jan Rijk: “It is moving to see that after all the misery of recent times yet there also can be tolerance. Music is obviously the way!”
During the concert of John Coffey in venue Gebr. De Nobel in Leiden the concert photographer Jan Rijk was moved by seeing two girls with headscarves on who turned out to be big fans of the Dutch rock band. “Then a little later one went crowd surfing, and I just had to capture this,” said Rijk.
Photo of integration and tolerance goes viral …
The girl in the picture would prefer not to generate too much fame for her person, but she would be happy if the photograph could bring about a change in the stereotype of ‘the Muslim‘, particularly at this time of hatred and destruction, she told Dichtbij.nl. “I also hope to have an effect on the Muslim community, because I know that there are more Muslim girls who also enjoy such music, but do not talk about it or are not allowed to go to the concerts by their parents.”
“I think my father will find this photo funny, but my mom will get really mad if she sees this, haha,” laughs the Muslim woman. She is proud and pleased with the beautiful picture. “Let’s hope that this, however unexpectedly, will be good for something and that this will lead to something positive!”
