Energetic Disco is Energetic Disco Girl's second album and the first album in Chapter 1. This is the band's signature album, containing a number of EDM songs, with high-energy disco melodies (Metro Vision, Energetic Disco, Flying Thunderstorm, Radio Signal), ambient chill beats (Charisma, Crescent, Antimatter, Rainbow Twinkle), and thundering drum-and-bass patterns (Electrosymphony, Lightspeed Cycles). Unlike First There's Morning, which is mostly peaceful music, this album has more energetic songs than peaceful ones, which is why this album has this name!
