Whenever I stumble across a song I like on youtube I download it into my personal music folder, I started this practice more than 4 years ago and I accumulated a large amount of socialist music from very niche spaces, spanning across a wide variety of languages. Because I see that nobody else is doing this specific thing on this site, I feel compelled to share this collection track by track, maybe it will lead to someone else also feeling the same inspiration that I felt when first listening to it.
The Internationale is a classic all can recognize, but this rendition in particular is my favorite. The inflection of the vocalist, distinct choices of instrumentation as well as the upbeat tempo give it an unmistakable energy which makes it stand out from other renditions of the song. As far as the musical group this originates from I sadly can't provide much insight, but surface level information says that they are politically active and involved in the fight for minorities rights in Japan, anti-war causes and support for Palestinian rights.
That was really fun! It would be a great song at a festival!
