It’s impossible to compile a list of post-rock records worth anyone’s time without going back to what is, kind of, the source. While not the earliest album presented here, it was one that went a great way to codifying the American post-rock sound: by, basically, doing whatever the hell it wants for 42 minutes. There’s jazz, plenty of it; swirling organs and marching drums; pulsing electro beats and chopped-up drifts of synthesised somethings. And much of what you hear across the record’s whole is, in some way, dabbled with on the every-direction-at-once 20-minute opener, Djed. The Taut And Tame is like Slint sped up to double-time and given a few ice cream scoops of funk for dessert; A Survey, meanwhile, is a sleepy and eerie exercise in manifesting dread entirely through aural means, slippery bass rustling its way through a swampy danger zone. The Slint connection came as no surprise, though – for this recording, Tortoise counted the Kentucky group’s David Pajo amongst its number.
