so i was listenign to Person of Co shu nie and then I search for Katharsis, so I was so fucking excited when I see this version of these two, they are my fave
Cö shu nie had some problems with the song there were some parts where her voice cracked but she did amazing , katharsis is a very hard song to perform anyway.
However I still don't think the roles of vocals are well-assigned otherwise it could be even more impressive. I just feel some parts should not be sung by micoon e.g. the cracked part you mentioned
It is clear that Miku can't express her talent as usual because of Tk's usual rhythmic dynamics. She would have blent easily if it was Tk's single, Melt ... at least there Tk's rhythmic dynamics are absent .
