Yamaguchi-based producer illrain has released "Chika (feat. T-STONE, Authority, TERU)" from his new album. This song expresses the determination to not use one's environment as an excuse, and the pride of carrying the weight of one's hometown on one's shoulders. It goes beyond the simple distinction between city and countryside, and explores the intersection of the cities and lives of each individual. The title "Chika" embodies the determination to move forward with one's own beliefs, regardless of one's environment.
