"Bell Meditation" is a highly minimalistic song with slowly reverbating bells and subtle background melodies, apparently devised for meditation purposes. It's beautiful, but has so little going on that it is painful to actively concentrate on it. It is music that is by all means meant for your implicit brain, thank you very much. Or, interpreting it another way, it is one hell of a build up to "Neptune".
"Neptune" goes back to a more normal D&LS sound with Lena's piano improv and Doc's tense ambience. The piano part at the very end sounds as if you had risen out of Neptune and were still dripping water.
Finally, "Andromeda" is another minimalistic piece based on a slow rhythm. I like it better than "Bell Meditation" due to the more open soundscape, free from the constraint of those endless bells. It feels like you are flying through space.
To close off, this is the D&LS album that demands the most imagination from the listeners' part to work, or at least a willingness to meditate a bit. I believe it's good at what it does, but it's utilitarian enough that under normal circumstances most of it is not easy to enjoy.
