Since this reading list was compiled, the field of Proust and music has been blessed by two further significant and very exciting publications (reviews of both by members of this project are forthcoming):
Joseph Acquisto, Proust, Music, and Meaning: Theories and Practices of Listening in the ‘Recherche’ (Palgrave Macmillan, 2017). See here for more information.
Cécile Leblanc, Proust écrivain de la musique: l’allégresse du compositeur (Brepols, 2017). See here.
Finally, there was an excellent conference on Proust and music at the end of October 2016 at the Fondation Singer-Polignac in Paris. If you look here you can see the programme and scroll down for video recordings of all the papers: enjoy!
