Kate Molleson talks about mind, body and soul with the Scottish mezzo-soprano Karen Cargill, as she prepares for concert performances of Bartok's Bluebeard's Castle with Opera North later this month. And Kate speaks to Anna Bull about her new book “Class, Control and Classical Music”, exploring the class barriers into classical music, together with the opera director Adele Thomas and the head of Hull’s music service, James Dickinson. The artist, audio investigator and Turner Prize nominee Lawrence Abu Hamdan muses on the role of sound within both the law and human rights, and describes how he turns his investigations into works of art. Plus Kate asks Daisy Fancourt about her new report for the World Health Organisation – a meta-analysis of 3000 studies examining the role of the music and the arts in improving health and well-being – and visits a soon-to-open pioneering care facility for people living with dementia at Harmonia Village in Kent where music is set to play a central role.
