A single minute of animation and one song about a mother's face, drawn while you watch. The restraint itself becomes the point. There's no narrative trick, no emotional manipulation, just a voice and hands moving across paper, and by the end you understand why someone needed to make this permanent. The kind of thing that sits with you longer than shows ten times its length.
Okaasan no Kao is a single-episode music piece in the form of an ekaki uta, a drawing song. The picture the song builds up is a portrait of the singer's mother, so the whole piece centers on bringing her face to the page through song.
