You are about to enter into Sweet Baby Jesus territory.
This is Kohei Gomi reworking the last 20 minutes of a live set at Blå, Oslo from 2007. The louder the volume, the more hypnotic it gets. It goes silent at around 20 minutes .... for a while ... then you get a "hidden track" of (erm...) high-pitched burping and farting noise birdsong (sort of ...).
Caligari, if you drop a "not bad" on this, I'm coming around to your house to kick you up the arse :)
CDr released on his own AMP label in 2010. This is another one of the resurrection releases that came out in Japan in a really small edition with only a reported five copies making it out to my half of the world.
