A very pleasant listen, perfectly suited for a quiet evening or as background music while your are relaxing. The music suffers from the same problem that most soundtracks often suffer from (even though this is not a soundtrack), it requires visuals (in this case the ballet)in order to make it memorable. Usually memorable tunes are McCartney's strength but here there is little that stays with the listener. The most memorable section is Movement 4 which has a distinctive melody. Distinctive that is until you have finished the whole album. The melody fades quickly much like waves on a shore (the same is true of the music as a whole).
In the past, McCartney has produced much stronger melodies in a non pop/rock setting. The just reissued "Family Way" soundtrack is very good example.
Note: All versions include a code to allow a free download of the live premier of this music. A nice touch but it adds very little to the enjoyment of the piece.
