Micah Silver's August 139 hz Personal Installation was, as its name implies, made for an installation, but it's actually better suited for headphone listening. On its surface, August 139 hz Personal Installation is driven by throbbing and appealingly fuzzy electronic pulses that bob and weave their way through the mix. Below that, however, are lovely whispers of static that give the album textural richness. The pacing of the record is outstanding, and the constant subtle changes in the static undertow help keep the album consistently engaging even though it never changes dramatically. The sounds on August 139 hz Personal Installation are less familiar than those on Brian Eno's Music For Airports, but Eno fans should appreciate Silver's warm, inviting ambient work.
