You cannot imagine how much it pleased me to hear voices entering contrapuntal writing for your Main Theme: it pleasantly tickled my ears which adore this kind of musical structure. The rest of the OST richly depicts different emotions, the melodies particularly harsh and expressive by the dissonance they create with the other instruments. It's daring, strange, and therefore creates a rather strong and disturbing general atmosphere. River of Memories is undoubtedly the most accomplished music from the point of view of the choice of instruments. Very beautiful atmospheres which can indeed perfectly illustrate the phases of the games musically, particularly focused on a complex and captivating story. Well done !
