If these are just the isolated vocal tracks, then there's a lot I, and probably lots of other Ethel fans, haven't picked up from listening to PD solely through streaming where a lot of bandwidth is not reproduced from the original...that bass humming that drops at 01:57 for instance, as well as a lot of little ASMR bits. I am beginning to think her production skills have been underrated as just 'competent' rather than sophisticated and subtle. And her vocal arrangements are inspired with little quirks and jumps.
I love how that low humming throughout the song sort of mirrors the groans heard later in ptolemaea, must be part of the way she so cleverly foreshadowed it in this song in addition to the flies. Thank you so much for sharing these, they truly deepen my appreciation for ethel's music!
