[Machine Translation] This album, SALU's 4th full-length album, is the catchiest album in SALU's history and was self-produced by a variety of track makers and producers, advocating the highest point of pop music expression from the perspective of a sensitive rapper surviving in Tokyo. The title "INDIGO" is a play on the word "INDIGO". The title "INDIGO" was inspired by the color indigo, which he used in the process of creating this album. The lyrical messages of the songs are about love for various targets, such as lovers, best friends, children, artificially intelligent robots, and social situations, and the theme of the album is to dye them with love (=indigo). The album is an "open work" that emanates from the full emotions of SALU's current state of mind.
