How about some epic OST-like piece of 8 minutes, telling a fanfic-level story written in the comments section? Here you go! This is quite commendable and amazing really, with not only the sheer length and thoughtfulness of the story and associated lore, but also that musical mastery of composing fitting parts to tell the different story parts, and to make it relentlessly intense for 8 minutes! This definitely took a lot of skill and passion!
This is available on the compilation album Equinity 04 Immersion!
