Breaking Free - the minds that changed music.

In The Essay this week, personal reflections on the revolutionary music and ideas of the Second Viennese School as they searched for an antidote to all the certainties and expectations of the past, and cast music on a new path of dissonance and discovery, shocking audiences then and now.

Tonight's essayist is Gillian Moore, Director of Music at Southbank Centre in London. She talks about Alban Berg's relationships with key women in his life, including his final operatic creation "Lulu".
