This is "Osorezan" ("Mountain of Terror"), the magnum opus of the enigmatic Japanese group Geinoh Yamashirogumi. The group consists of more than a hundred members, and apart from making music, they have been doing world-music research for decades. Strangely, this group is almost unknown outside Japan.
Don't believe in any urban legend; this group can and did perform this piece live.
That was amazing. So scary I couldn't listen to the whole thing. No kidding. I'll have to come back to that, maybe when I'm straight...
