Sofian Saidi found out that cheekiness prevails, in North Africa too. Uninvited, during weddings, he demanded to be given the mike – and kept going until bride and groom and the entire room were rocking. At 17 he fled to Paris. Did the rounds of the cabarets. Today, this rebel of Rai music no longer gatecrash weddings. His rough voice resounds in the smart Elbphilharmonie concert hall. He brews a feverish mix of Arabic, Jewish and Spanish sound ingredients.
