今年の7月に横浜アリーナでの解散ライヴを控えるアイドル・グループの、最後のオリジナル作。いまとなっては数多く存在する〈ロック×アイドル〉なスタイルの遥か先を行く最新型にして決定盤と言っていいでしょう。GLAYHISASHIがギターで参加した“primal.2”は初めての本格的なバラードで、エッジの立った曲ばかりを送り出してきた彼女たちが歌うのがあまりに新鮮。笑えるくらいに切ないJ-Pop仕様で素直に感動!

[English Translation]
The final original release from the 'hugging and high-touching' idol group BiS (Brand-new Idol Society) who announced their final performance to be this July at the Yokohama Arena. Amidst the already trending 'rock * idol' format and the bunch of bands alike, this would be by far the most cutting edge but yet classical piece of work in the field. "primal.2" is the group's first serious ballad with the memorable appearance of HISASHI of GLAY on guitar, which creates a pleasantly fresh contrast to the close-to-shocking edgy songs they have been performing in the past. The album is so nostalgically close to authentic J-Pop that may make you want to almost cry and laugh at the same time through sheer joy and unexpectedness.
