I just watched the pilot of this show, and I was impressed with the music in general, but especially with the oboe playing of its lead character. I looked up the actress who plays this role, Lola Kirke, and it seems likely that she’s not actually the one playing, even though she does a pretty good job of looking like she is. Google isn’t getting me anywhere, and even IMDb, which lists the cast and crew down to the hairdressers and craft services, isn’t saying who really plays the music.
François Leleux is the oboist credited on the soundtrack album.
