[4] On April 23, 2021, it was announced that the band would release their first full album after resuming activities on June 9, which is "Rock Day".

[6][7] Additionally, Shiina said the album's chord work as "may be more jazz than funk", citing Miles Davis and Roy Hargrove as similarities.

Tracks 6 ("青のID", "Blue Period") and 8 ("赤の同盟", "Red Alliance") are both named after colors, while odd-number songs all feature male vocalists.
