Damn right, WATAPACHI are a production/DJ duo from Tokyo, Japan. Let the carnage ensue.
What I particularly like about them is how in tracks like the above "Play" they achieve the hard-hitting effect that is desired not through ostentatious, in-your-face high pitched leads, but rather through understated but definitively acidy broken up lead lines.
And now for something a bit gritter. Grind just gets so damn dirty, especially compared to the cleaner type stuff we saw above. Really really sick.
Just for the purpose of showing their versatility, here you can listen to a Floss-type, trapstyle rythm, and you can listen to some of their more chilled out/trippy stuff here, here and here.
These guys are sick, and this is just a selection of some of their many many great tracks, so check them out properly for yourselves at https://soundcloud.com/watapachi.
