Opinion – Arts, media, GazaIn the summer of 1988 the music festival producer Tony Hollingsworth organised a concert at Wembley Stadium in London to celebrate the 70th birthday of Nelson Mandela. Take, for example, Together for Palestine, a concert to be held tonight at Wembley Arena – the huge indoor auditorium next to the stadium that hosted that Mandela birthday concert 37 years ago. Wembley signed a contract, YouTube finally consented to streaming the event, and – most importantly – artists agreed to appear. And so this evening, Wembley hosts the biggest cultural event in support of Palestinian rights since the destruction of Gaza began. Appearing on stage will be, among many others, Oscar nominees Benedict Cumberbatch and Guy Pearce, musicians Bastille, James Blake, PinkPantheress and Damon Albarn – and Palestinian artists such as Saint Levant and Elyanna.
