OM's sound is set in stone. You know going in just exactly what you're going to get. Rock Solid. You could set your watch to it. But it is a sound that is well honed rather than narrow in scope. A lesser band wouldn't be able to pull it off for long. OM though belongs to a rare breed- think AC/DC or Dead Moon- who are able to achieve constancy without (for the most part) sliding into redundancy.
For a band whose music almost seems constrained by the limits of an LP side, it's surprising that these guys even mess with doing 7"s. I suppose the fade out suggests that this could (and maybe did) carry on ad infinitum.
Ben Chasny weighs in with a wordless incantation set to some fuzzed out, reverb drenched guitar action that recalls the earliest Six Organs output or perhaps the first Badgerlore record. Probably a relatively inconsequential track in a discography that seems to be approaching canonization in some circles, but a nice slab of psych guitar noise nonetheless.
