These two songs, released as a limited first edition release by Perfume, break new ground in electro-pop.
"Unnatural Girl" is themed around artificial beauty, and Nakata Yasutaka's meticulous programming shines through. "Naturally in Love," in contrast, features a strikingly organic melody, expressing the contrast between technology and humanity through music. The DVD includes conceptual video works, which are also highly accomplished as visual art.
