This is pure instrumental music. It is also electronic ambient, and has an experimental and free form quality that gives it its freshness. In the forefront, the jazz style drum rhythms keep you guessing as to the natural beat, and the spacey motifs are reminiscent of Orbital. There is plenty to listen to in the structure of the music, and the opening track, Ark, has an irresistible feel of perpetual motion, driven on by a persistent monotonic bass-line and slow heavy drumbeat with crashing cymbals. The final track, Aphelion demonstrates inventive use of bowed instruments, and is a true masterpiece. My only gripe is that the whole experience ends in just over 40 minutes, hence the 4 stars.
