Greengreen" includes 6 songs, in which the title track "Redred" received attention thanks to its youthful musical color, combining rebellious images and messages about creating a private space instead of following pre-existing templates.
According to the introduction from the production crew, this album focuses on exploiting the creative spirit and personality of the members. Many stages in music production and concept building are said to have the direct participation of the group.
Not only achieving high sales, CORTIS also recorded positive responses on social media platforms and international charts after the album was released. Many "Redred" performances quickly spread on TikTok and short video platforms thanks to strong choreography and catchy rhythm.
Currently, the management company has not announced the next promotion plan, but with the current growth momentum, CORTIS is expected to continue to become a noteworthy name of Kpop this year.
