...its not an ep. its an lp. All of Explosion's stuff is concept. "The Earth Is Not A Cold Dead Place" more or less concept is love based.
From my aspect, seems to be related to a time of year- with all the excitements of transportation and the progression of man in this way. The only song that doesn't quite fit is frontier psychiatrist.
.. Frontier Psychiatrist isn't on the album.
Anyhow, I don't have the actual CD, so I suppose I can't argue with you. What I can compare to, would be every single Godspeed You! Black Emperor album. And Mono's "Are you there?"
blabla
I say you forgot Deathspell Omegas "Si Monumentum Requiems, Circumspice", which is probably the best thing that ever happened to black metal.
