Yes, Zico is in a K-pop group. He debuted as the leader and main rapper of the South Korean boy band Block B in April 2011. While many modern fans know him primarily as a hitmaking solo artist, a prominent record producer, and the founder of KOZ Entertainment, his roots are firmly planted in the idol and underground Korean hip-hop scenes through Block B.
Understanding Zico's place in the K-pop industry requires looking past simple solo/group labels. His career spans underground mixtapes, stormy agency legal battles, massive solo chart dominance, and leadership roles in shaping newer generations of talent.
The Block B Era and Underground Roots
Before stepping into the mainstream spotlight as an idol, Zico (born Woo Ji-ho) built a reputation in Seoul's underground hip-hop circles. He released underground mixtapes under the moniker Rima before adopting his stage name. In 2009, he joined Stardom Entertainment as a trainee, where he crossed paths with other future industry figures.
On April 15, 2011, Zico officially debuted alongside Taeil, B-Bomb, Jaehyo, U-Kwon, Park Kyung, and P.O in Block B.
- Creative Control: Unlike many conventional idol groups of that era, Zico took charge of writing, composing, and producing the vast majority of the group's discography.
- Musical Style: Block B carved out a rebellious, energetic niche with tracks like "Nalina," "Very Good," and "Her," blending aggressive hip-hop beats with catchy pop hooks.
- Group Status: Even though members have pursued independent paths and completed mandatory military service, Block B technically remains an active unit, occasionally reuniting for special performances.
Transition to Solo Stardom and Fanxy Child
Zico's transition from a group leader to a powerhouse solo act happened gradually. In 2014, he dropped his official solo debut single, "Tough Cookie". This release proved he could command charts on his own terms without relying strictly on the Block B brand. Subsequent solo releases like "Boys and Girls" and "Artist" solidified his status as a digital monster in South Korea.
He also expanded his creative footprint by co-founding the alternative R&B and hip-hop crew Fanxy Child in 2016. Alongside artists like Crush, Dean, and Penomeco, this crew allowed Zico to explore smoother, more experimental sounds outside the strict boundaries of traditional K-pop idol music.
Founding KOZ Entertainment and Producing Boynextdoor
In November 2018, Zico chose not to renew his contract with Block B's agency, Seven Seasons, though he did not officially leave the group itself. He established his own independent label, KOZ Entertainment, in 2018 to foster creative freedom.
- HYBE Acquisition: In 2020, HYBE Corporation acquired KOZ Entertainment as part of its multi-label expansion strategy.
- Mentorship: Zico transitioned from a group member to a executive producer, spearheading the launch of HYBE's boy group Boynextdoor. He actively writes, arranges, and produces for them, passing down his hands-on approach to music production.
Chart-Topping Solo Success
Zico's career reached new heights with viral sensations and massive collaborations. His 2020 single "Any Song" sparked a massive social media dance challenge trend, dominating South Korean music charts for weeks.
In 2024, he released the smash hit "Spot!" featuring Jennie of Blackpink. The track dominated international markets, hitting number one on the Billboard World Digital Song Sales chart and securing a top-ten entry on the Billboard Global Excl. U.S. chart. These milestones proved that his influence stretches far beyond traditional K-pop group boundaries into global mainstream pop culture.
