Headliner USA E6: Joshua Bell | The Sound of a Stradivarius

We chat to one of the world's finest violinists, Joshua Bell, about his life in music, picking up the violin at four years old and turning professional by 14, experimenting on the New York subway, and creating the Joshua Bell Violin with virtual instrument manufacturer, Embertone, which means any budding composer can have a go at emulating the tone of his multi-million dollar Stradivarius.
