This is the impassioned and exhilarating story of the composers who dared to challenge the conventional world of classical music in the 20th century. Traversing the globe from Ethiopia and the Philippines to Mexico, Jerusalem, Russia and beyond, journalist, critic and BBC Radio 3 broadcaster Kate Molleson tells the stories of ten figures who altered the course of musical history, only to be sidelined and denied recognition during an era that systemically favoured certain sounds – and people – over others. A celebration of radical creativity rooted in ideas of protest, gender, race, ecology and resistance, ‘Sound Within Sound’ is an energetic reappraisal of 20th-century classical music that opens up the world far beyond its established centres, challenges stereotypical portrayals of the genre and shatters its traditional canon.
