I thought that was kind of interesting as well. I guess it's because he equates Apollo with Baldr, about whom he has already written one album (which is what makes me wonder if there will be more than remake of a song from Daudi Baldrs). Since he said he was looking for something pan-Indo-European, I'm surprised that he didn't instead pick Zeus (and his variants like Jupiter, Dyaus Pitar, and Tiwaz/Tyr), who is definitely the oldest god in the entire pantheon. If he can stick to the tentative release schedule of April, we should hopefully be able to hear at least a preview sometime in the near future.
