Lorca was a friend and collaborator of the composer Manuel de Falla.
Falla went to Paris and met Debussy and other so-called "impressionist" composers.
The baritone Charles Panzera, hero of Barthes's "The Grain of the Voice," knew many of these comoposers personally.
Roland Barthes reportedly took singing lessons from Panzera.
So I got from Lorca to Falla [UPDATE: Barthes I mean] in four steps. This is a very fun game.
