It starts off with looped clicks, sounding vaguely plastic-esque in timbre. Following this is a drone, a very thin sounding one at that. Various other percussion come in at points, some also oscillating rather violently to a point that it takes center focus.
The only more regular percussion present is a tom sound, it adds a slightly naturalistic tone to the piece, but it does sound like midi so that only goes so far. The tom also begins to slide around in pitch and velocity, distorting somewhat on the harder hits; among this is more processing on the tom.
What is a bit different in comparison is the lo-fi/no-fi aesthetic and production. The drone sounding sort of thin and cheap (in a good way) adds a lot to this, alongside the clicks and the fact that not too many changes in texture are made. Perhaps in working with a cheaper set up, ones capabilities would be limited. The artwork also follows the lo-fi idea, with what resembles a MS paint doodle that was on a smaller canvas than what it has been stretched to, gaining this compressed sort of look.
This reminds me quite vaguely of Steve Reich's Different Trains. I think mostly because of the consistent pulse, and the metal percussion in Different Trains sounds similar to the clicky pulse in Quinquennial. Over all a really enjoyable piece of lo-fi rhythmic experimentation.
