Sadly this is not the full show.
Finally found this video after it got DMCA'd.
Ok, the guy that jumps on the stage is motsu a japanese rapper.
Fripside is nanjo (singer)and Satoshi Yaginuma(synth player).
Satoshi Yaginuma was part of a group that included motsu.
it's cool that motsu was part of this live show cause he brings energy.
