Hasunuma's sound work, which can be said to be a memory of recent years, shines with a variety of artists, including guitarist Jeff Parker, who is known for releasing works from International Anthem and Nonsuch Records, and Keigo Oyamada (aka Cornelius), who has performed with him live. Keiji Haino, who continues to collaborate from time to time with Hasunuma, playing various instruments, New York drummer Greg Fox, KOM_I's generous and warm voice, and Aragaki Mutsumi, who lives in Okinawa and plays the sanshin and sanba of the traditional instruments in Okinawa. Guitarist Shuta Ishizuka, who is also active in Shuta Hasunuma Philharmonic Orchestra, and Otonashi Fumiya of Japanese traditional instrument sho are participating as guest players. The sound of various musicians with different activity areas and musicality gathers, raising the contrast of the sound of this album. The sound work, which includes techno, ambient, jazz, post-classical, and even contemporary music, is difficult to identify in sync with Shuta Hasunuma's own wide-ranging activities. However, it is this unspecified nature that creates the sounds of free and airy sounds. It is the first studio recording album in seven years since the singing work Melodies (2016). It will be the first release in 15 years since Pop Ooga (2008) as an instrumental work, and it will be a long-awaited release. In terms of production, the album's core instruments were recorded and mixed at private studios in Hasunuma's Brooklyn and Tokyo.
