Tom Service explores Luciano Berio's Sinfonia - an iconic piece of the late 1960s modernism, scored for orchestra and eight amplified voices who speak, whisper and shout texts by Samuel Beckett and Claude Lévi-Strauss. This groundbreaking work also incorporates a mass of musical quotations, from Bach to Stockhausen and everything in between. Tom's witness is the virtuoso sitarist and composer Jasdeep Singh Degun, who like Berio, took Monteverdi's opera Orfeo and reinvented it. Produced by Dom Wells
