Following his tenure in top '90s K-pop boy band H.O.T., KANGTA has honed his craft as a singer and songwriter. His 2001 solo debut, Polaris, revealed a knack for poignant ballads and gentle midtempo R&B. Subsequent songs like “Pine Tree” have featured lavish, heart-wrenching swells of strings that build to a climax, while others, like “Confession”, have the stripped-down vibe of an unplugged set in a café, bringing his sincere vocals to the foreground.
