[Machine Translation] Lyrical melodies, technical performance, and expressive, ever-changing vocals... THE SHEGLAPES' long-awaited 1st mini-album, a "substandard girl band" performing dramatic metal with an emphasis on storytelling! This album is composed of 6 songs that focus on storytelling and worldview throughout the album. As the title "BACK'n'FORTH (Back and forth)" suggests, the album is a story of different historical backgrounds and themes that unfolds one after another without a break. The album is a fusion of Keiko Kanie's expressive and ever-changing voice and her technical and powerful performance, and it is no exaggeration to say that it is a "new frontier of girl's metal" that transcends the boundaries of the metal genre and is unprecedented.
