In the first of a new series, Dermot Clinch and Tommy Pearson present an interview with Mariss Jansons, the new music director of the Royal Concertgebouw Orchestra. They also look at the legacy of Charles Ives as the CBSO begins a series of his music: was he an insurance genius and an amateur musician, or the father of American music? And singer Catherine Bott investigates an ever-present concert phenomenon: the audience cough.
