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.
