48: Pianist Nicolas Hodges discusses Messiaen's Des Canyons aux étoiles

Nicolas Hodges appears at the BBC Proms 2019 in a performance of Messiaen's Des Canyon aux étoiles. Here he discusses the different ways birdsong sounds across the world, how eight weeks when he was a teenager made contemporary music inescapable, and what happens in the moment between the final note of a piece of music and the applause beginning.
