One more album for deep work/study:
Made by Thomas Köner in 2002, it is made up of one track called Daikan, meaning the coldest part of the year, according to traditional Chinese calendar.
Album certainly is cold, but in the way that sharpens one’s mind (after a cold shower).
No sudden shifts, and sometimes you can experience transitions as in 40:54 (be sure to have headphones for full experience).
For this album, you need to have patience, but it pays off in the end. :)
