Every Sunday afternoon for over 30 years now, Marjorie Eliot has played a jazz concert in her Harlem apartment for anyone who comes. It all began on a Sunday morning back in 1992, after she was faced with an unimaginable loss.

In this episode of Sideways, Matthew Syed explores how music has allowed Marjorie Eliot to look for joy within the deepest of losses. And through the history of jazz itself, he tries to understand how music can become such a powerful, even transcendental force.

With actress, playwright and musician Marjorie Eliot; singer, composer, actor - and Marjorie’s son - Rudel Drears; and Dr Tammy Kernodle, musicologist and Professor of Music at Miami University in Ohio.
