Artist Profile
cos9nA vocal unit formed by nine cargo drivers.
The name "cos9n" comes from the nickname of Takeshi Kosugi.
While it does have some meaning as a nickname, the name was also chosen because the graph of cos(9n) in trigonometric equations resembles vibrato, thus considering its connection to music.
