They’re both Japanese. Let’s just get that fact out of our way at once. Why oh why are japanese so good with jazz?
It’s probably the same as electronics. They take revenge from the western world by doing the things they take from westerners better than the west. Yes, don’t be fooled by their smiling toy faces, Japs are mean little bastards when it comes to jazz.

With this classic yet never out-fashioned maximal style of nippon-jazz (just the way GP likes it), they’re creating, in their own terms, an impact similar to their elder brothers Kyoto Jazz Massive or like what Jazztronik has done with
acid jazz…With more italian suits and golden teeth of course.
