There are a few records that exist entirely in their own universe. Although they can be placed in the context of some sort of musical movement, they are truly unique and offer an insight into the mind of an alien. Oar is one of these records. (I've talked about similar concepts in my discussions of Sun Ra's works.)
It's hard for me to write about this, as this music exists in a world completely outside of my own experiences. Listening to it turns me into a reality tourist briefly shedding my overanalytical science perception in favor of a much looser existence based upon floating in melting martian ice caps. Layered vocal tracks, open strings, and reverb create an emergent phenomena that absolutely must be experienced. Dangerous, damaging psychedelia that is orders of magnitude trippier than even the most fuzzed out of all guitar solos.
And I can't help but compare the vocals on "Diana" to US Maple. Oops. Oh and motherfucker was in Moby Grape too. Remember that shit from back in the day?
