EDIT: A little more info on this
The head of musicoms is guitarist Masahiro Komura (小村 雅弘), who goes by "COM." The musicoms site has perennially been not super forthcoming about info, so I can't really tell if it's
only him producing music or if there have been other people too.
"COM" is credited with guitar on this album
