The Mount Fuji Doomjazz Corporation is an eccentric band, but I think their name already gives that away. Their music isn't exactly loud and in your face, though.
Using horns, electronics, and ton of indescribable textures, Mount Fuji fades the borders between drone and jazz music with vast improvisational soundscapes.
The band's latest album is Anthropomorphic. Stream the entire thing below, and grab it on their bandcamp for five Euros if you dig it.
