Splitting ~90 minutes of material between two tracks, this album from the Scottish group of Ommadon focuses on developing its instrumental doom through a set of central riffs, letting their shaping of bass resonance and percussion do practically all of the work.  Grinding along on the riff cycling, the little tweaks in alignment of beats and chords provide the majority of variance, and while the sustained patterns are impressive in a way, until the last few minutes, the extra length doesn’t really do anything that isn’t communicated within the first half.  Good as background doom atmosphere, but very resistant to active listening.
