So I'd listened to Boards of Canada's Tomorrow's Harvest at work a couple times over the past week. Last night I finally had time for a proper sit down and listen on the he-man stereo, in the dark late at night.
And guess what? Turns out that whole album is nightmare fuel. Instead of streamlining and refining their work to the utmost polish, they'd used their years since the last album to pack it to the absolute brim with half-audible voices, up to and including (on "Telepath") a staticky voice in the background coaxing a numbers radio station voice to "do it again." The melodic numbers serve not so much to provide relief as to provide the shallow reassurance that although the horror is real, things are okay as long as it hasn't fulfilled its purposeless inevitability yet.
I think I slept about 45 minutes between going to bed and going to work this morning.
I tried only once or twice, but maybe not with the proper level of attention, and could not get engaged in the music...helped me sleep more than anything else :)
