If you want to banjanx the algorithm, instead, watch a few Kyoto Tachibana Senior High School Band videos (e.g. https://www.youtube.com/watch?v=kIouDxRfTb8) or Shimane Prefectural Izumo Commercial High School Band videos (e.g. https://www.youtube.com/watch?v=VPLzr3cuFtk).
There appears to be an enormous algorithmic weight to those. Just a few such videos completely swamped my recommendations with Japanese marching bands a couple of years ago. Simply finding those two to copy their URLs into this post has immediately put two further band videos into my recommendations.
Typically, all these videos have under 1000 views. I am at a point where I might even write a user script to hide every video under 1000 views.
