あたりまえつこのうた

Compilation of songs created for the "あたりまえってなにかしら" ("Just what is obvious?") segments on the カガクノミカタ (Allies of Science) series aired on the NHK Eテレ educational television channel. Each track on the release (the title of which translates to "The Songs of Atarima Etsuko") concerns the character Atarima Etsuko reflecting on a particular topic, including genders, animals, points of view, curiosity and the future. The release includes the album on a CD, and the animated segments of every track on a Blu-ray Disc. Both are packaged in a standard blue Blu-ray case which also includes a 28-page booklet.
