NORIKIYO's new song was produced by KOYANMUSIC, a rapper, trackmaker, and mix engineer who is also a member of the rap group SD JUNKSTA.Surprisingly, this is the first time for KOYANMUSIC to produce NORIKIYO's solo music, and the song titled "Samidare" will be a rarity in NORIKIYO's career.The simple structure of the song, with its melancholy guitar loop and strong, simple beat over which NORIKIYO's flow runs, makes it a song in which NORIKIYO's message shines through.
