Not sure if the source tune is ineligible for OC ReMix due to being a licensed track not written for the game; would be a shame if so.
Super classy source tune, so let's see what's up with this treatment. Breakbeats! Interesting giving the brass a more muted sound and leaning more on the breakbeats and piano, but everything's balanced well, IMO, so none of that observation's a complaint.
Interesting to build around just one or two melodic segments, but there's enough textural dynamics to retain my interest. I can see some saying 5 minutes is too long and that it should change up more or explore other areas of the theme. To me, this could use some further variations, however, the interpretation of the theme's already substantive enough. Cool approach, and always love to hear the Rukunetsu spices in play!
