Taking its name from George Gershwin's When do we dance?, the latest album for Naïve from Lise de la Salle finds her taking to the dance floor as she travels from her native France to Eastern Europe, Spain, Latin America and finally the USA. James Jolly caught up with her to talk about the concept behind the album, playing the music of Maurice Ravel whose Valses nobles et sentimentales take centre stage in the programme, and how she tackled playing jazz.
