Sexcial Judo Uniform is a single by 三連玉袋 333tamabukuro that was self-released in 2013. This band claims that the music they make is techno but it’s actually experimental.
This is an interesting track since it is a field recording but with vocals recorded over it. The recording consists of people doing judo matches, it has some nice natural reverb, and sounds like people fighting because it is people fighting. Scuffling, yelling, thumping, and banging. Repetitive vocals are spoken over it while a loop of what sounds like breathing comes in and out.
This is a pretty cool track, listen and download below.
