Daniel Barenboim’s West-Eastern Divan Orchestra is a youth ensemble comprised of equal numbers of jews and arabs. “This orchestra cannot perform in Jerusalem, for fear of disruption, or worse, from one set of extremists or another. This orchestra has never performed in any of the countries from which its members are drawn. Last year there was a single, heavily guarded, performance in Rabat in Morocco – the only one to date in an Arab city. Security for these youngsters, as they make their way to and from their homes, is such a problem that on occasion the Spanish government has even provided diplomatic passports. And – most chillingly of all – the concert programme contains no names.”
