Here's something old for your files. Takaki's old band, ASS'n'Arrow.
and here's a picture from those days.
At about that same time, Kousuke was doing vocals for metal band, Plasma Jet.
I'm not completely confident, but I do believe that this album is Kousuke on vocals (pretty freakin' awesome album if you're into death metal).
I hope you've enjoyed this brief moment back in time.
