Organist and pianist James McVinnie's new album 'Dreamcatcher' is a beautiful series of works by contemporary composers including Nico Muhly, John Adams, Giles Swayne, Gabriella Smith, Meredith Monk and others, all based around ideas of imagining – be that to do with memory, architecture, musical form or social justice. He joins Editor Martin Cullingford in this week's Podcast to talk through the programme, and about the sound world he's created for this captivating recording. 'Dreamcatcher' is available on the Pentatone label from next Friday, January 17.
