Tramuntana. The Tramuntana wind not only swirls round the Catalan landscape: it can drive you insane. It has gusted through the lives and imaginations of many artists, including Bunuel and Salvador Dali. Neil McCarthy sets out from Dali's hometown of Cadaques with wind guide Eliseu Huertas i Cos to find the Tramuntana before it finds them. Presented in surround sound. Producers Mark Burman and Neil McCarthy
