Guest List: ZICO

Block B's ZICO rose from the underground through the K-pop industry to become one of Seoul's most respected—and most sought-after—rappers. His self-assured rhymes play well off of talented singers like Dean and Hyolyn on their smooth R&B joints. And he's not shy about showing off in the presence of veterans like Dynamic Duo, unleashing tricky verses that elevate him above a mere feature credit.
