The listing, Soundtrack CD: The Door in the Floor has ended.
I liked the music, but my wife thought it was too sad. Allmusic.com had this to say:
Brazilian pianist Marcelo Zarvos, who plays piano on many of the tracks, moves very slowly, creating glacial musical textures with sustained notes and chords picked up by strings that rise and fall gently like waves along the shore. All is certainly not well in East Hampton (i.e. in the movie), but the troubles clearly are emotional and largely internal, and the music expresses calm sadness for much of its running time.
