Tom visits soprano and Early Music specialist Dame Emma Kirkby ahead of a concert celebrating her 70th birthday this month, reflecting on her career and the way she's still active, coaching younger generations of new singers.

Also, we take a look at how string quartets replace departing members and the challenges for everybody of adapting to new, both personal and artistic environments - with contributions by the Fitzwilliam and the Doric Quartets.

Tom is in Southampton to hear the hidden voices of nuns and convent music with Laurie Stras and Deborah Roberts, who are bringing this polyphonic music back to life with their ensemble Musica Secreta - and he hears about a remarkable new discovery, a polyphonic work not heard in more than four centuries.

Also, the impact of Brexit on British musicians working in Europe and how they're planning to adapt to new immigration and travelling rules.
