Their track “Ensō” is dedicated to the Japanese symbol for enlightenment, strength and mu (the void). It is characterised by a minimalism born of Japanese aesthetics. Drawing an Ensō (circle) is a special Zen practice. The circle may be open or closed. In the former case, the circle is incomplete, allowing for movement and development as well as the perfection of all things. Zen practitioners relate the idea to wabi-sabi, the beauty of imperfection.
The sonic circle which the producers decided to depict, sounds nothing less than perfect and is a great choice in case you want something uplifting and easy on the senses.
