What songs would you say best represent Nefolian music and which ones represent Lunar music?
I'm still working on figuring out the Runnian/Lunar culture at the moment. But since it's derived from Nefolian culture, I'd say there's quite a bit of overlap.
Nefolian is certainly Celtic in its feel. Part of that is due to my love of the music and culture... I have a good idea that my ancestors probably were Celts waaaay waaaay waaaay back when. So I'm naturally drawn to it.
A lot of cultural influence came from the music of the band Ceredwen. Here's some samples for you:
Tir Aur (The Golden Land) -- Actually where I first found Aur's name!
Y Bryn Gwyn (The White Hill)
I've owned both of their CDs for a very long time and the sound reminds me of what you'd probably hear in Nefol and in the Gatherings.
