New title from the spin-off project of the "Gundam Song Cover Albums for Adults" series by Hiroko Mogiruchi. Unlike the previous trilogy, which featured collaborations with a variety of artists, all of the songs are performed with a full orchestra in order to express the world of Gundam even more deeply through music. The songs are selected from various Gundam songs from various eras suitable for orchestration, including the self-covers of Hiroko Moriguchi's representative songs "Mizu no Hoshi e Ai wo Komete" and "ETERNAL WIND - Hohoemi wa Hikaru Kaze no Naka -." The limited first edition includes CD-DICS2, which contains only the orchestral performance, and a Blu-ray disc containing the music video of the lead song and a making-of featurette that can only be seen on this disc. The sleeve case is newly drawn by illustrator Tsukasa Kotobuki, who has created the illustrations and jackets for all the albums in the series.
