This is a book consisting of a study of Ryuichi Sakamoto's keyboard solo parts in Media Bahn Live and musical scores. - Title: Ryuichi Sakamoto Media Bahn Live Keyboard Solo Study I read it once after purchasing it and then stored it. There are scratches on the entire cover. There were pencil markings on a few pages, but I erased them with an eraser. There is no problem with reading it, so please consider purchasing it if you don't mind.
