masaru sato (satoh)

Hi, I'm just curious about film composer Masaru Satoh - Mr Bungle covered a few of his pieces on the Disco Volante tour, and from memory Zorn once mentioned a Satoh collection when listing his favourite albums ever. Can't find much info, so I'm just wondering if anyone has any of his stuff, what it's like? Does anyone know where the pieces Mr Bungle covered can be found? Could be a good starting point... Thanks, Julian.
