Ancient Moon
Ancient Moon are quite a mysterious project for the three members act under the names of J, O and B, and nothing more is known. Apparently these guys hail from Belgium, France and Switzerland. I think Vvltvre is their first mutual effort, and it consists of one single piece, called Preastigitum Altareas, clocking almost half an hour.
[personal note: I do appreciate the fact that the sole track and the album itself do have another title]
