A Lebanese rock band has been banned from performing in Jordan because the lead singer is gay.

Mashrou' Leila, who have been described as “the soundtrack to the Arab spring,” are known for lyrics covering such topics as homosexuality, gender equality, and political and religious freedom.

According to the Guardian, the band released a statement on Facebook informing fans that authorization for a performance in Amman tomorrow night has been withdrawn.

The statement reads:

“The written justification officially provided is that the performance would have been at odds with what the ministry of tourism viewed as the ‘authenticity' of the site, despite the fact that we had the chance to perform for you at the same specific site three times in the past and had followed the same permit procedure before the competent authorities.

“Informally, the story is much more problematic. We have been unofficially informed that the reason behind this sudden change of heart..is the intervention of some authorities. Our understanding is that said authorities have pressured certain political figures and triggered a chain of events that ultimately ended with our authorisation being withdrawn.

“We also have been unofficially informed that we will never be allowed to play again anywhere in Jordan due to our political and religious beliefs, and endorsement of gender equality and sexual freedom.

“We denounce the systemic prosecution of voices of political dissent. We denounce the systemic prosecution of advocates of sexual and religious freedom. We denounce the censorship of artists anywhere in the world.”

The band also praised Jordan for having some of the most “supportive, beautiful and kind people”, saying it was the “only place where we get to perform for our Palestinian audience”.
