I'm gratified you had a good impression of it.
There is a full concept behind it and a proper list of the Silmarillion tracks i did over on Soundcloud, in fact chronologically the oldest thing placed on the platform as track 'I' is the June 2022 version of the Eärendillinwë and then through the first hundred tracks just generally I released, I tried to sneak in now and again another track which would take us to a different part of the book. There were later additions but much more slowly.
I tried to swing it during this jam in a way that people didn't really have pre-knowledge that I had made the other ones until fairly late in the rating period, re: 'don't manipulate the voting' meant for most jams
