This is one of those incidental music sound tracks that is best played while doing things. Not much of a sit down and listen CD. I personally loved the themes when I saw the episode, so the CD was an obvious buy. From ambient to mildly active, this is a calmer Doctor Who music CD. All synth sounds. 7th doctor era. More custom sounds used in this one than the other DW soundtracks by this musician. Mark Ayres does an excellent job of enriching the mood of the episode with this fine music. As incidental music should be.
