Usually music is self-sufficient. It offers you its mood, its idea. You can accept this or say "nope, it is not for me". This music offers you the partnership. Monotone simple rhythm, which lasts for 22 minutes without changes, forces your imagination to construct new patterns, the constant appearance of different sounds (rustles, tinkles, knocks, crackles and etc.) makes this structure so manifold that you have no way but to draw in your mind the huge amount of curious pictures. Amazingly!
