An OST entirely on the piano? Surprisingly, it works very well. The richness of this king instrument makes it possible to approach so many different styles and registers without ever causing weariness. And this is all the more true if the writing for the piano is well done, with a pleasant playing, the use of the sustain pedal and various nuances. Here, each melody is clear, and contributes to the listener's escape. The improvisational colors make the whole thing easy to listen to, pleasant, without ever being able to anticipate what will happen. The introductory theme being the only one to seem strange by its somewhat disjointed appearance, but which may very well be suitable for displaying a logo or other graphic syncho effect with these unstructured notes. The rest is pure meditative bliss. Well done !
