San-E mentions Zico in his interview with HiphopLE
Q: Do you personally like any rookies of recently?
San-E: Rookies? Recently? I haven't listened to them deeply, but the rookie rappers I really like are Okasian, New Champ, and Zico. I want to work with them. Okasian I've known for a while and he's always done well since way back. Now he's shining his light. New Champ I've seen several times with Answer and Youngin hyung. As for Zico, I've seen him before when Cho PD hyung performed back then. I saw his stage with Hyuna and he looked so cool. Damn.
