What Is the 4th Generation of K-Pop?
K-pop fans love to organize their favorite music into "generations" — loose eras defined by the artists dominating the scene, the production styles in vogue, and the cultural shifts happening around them. The 4th generation is generally considered to have kicked off around 2018–2019, with its golden era running through the early 2020s and beyond.
What sets 4th gen apart? Heavier production, darker and more experimental concepts, a stronger emphasis on individual artistry, and an unprecedented level of global fandom engagement driven by social media platforms like TikTok and Weverse.
Key Characteristics of 4th Gen K-Pop
- Concept diversity: From futuristic AI aesthetics to raw, streetwear-influenced performance styles.
- Self-production: Many 4th gen idols write, produce, and co-direct their own content.
- Global-first strategy: Groups debuting with English lyrics, international members, and overseas promotional schedules.
- Short-form content: TikTok challenges and YouTube Shorts are now essential parts of every rollout.
Groups You Need to Know
Stray Kids
One of the most self-driven acts in the industry, Stray Kids — particularly their in-house production unit 3RACHA — craft much of their own music. Known for chaotic, high-energy performances and a distinct "loud and proud" sonic identity, they've built one of the most dedicated fandoms in K-pop.
aespa
SM Entertainment's 4th gen girl group introduced the concept of "ae" (avatar) counterparts for each member, creating a full multimedia universe. Their sound blends hyperpop, electronic, and classic SM polish, and tracks like Next Level became cultural touchstones.
ITZY
JYP Entertainment's answer to the 4th gen girl group wave, ITZY built their identity on self-confidence anthems and sharp, choreography-heavy performances. Their debut track DALLA DALLA broke records and set the tone for a new kind of girl group narrative.
TXT (Tomorrow X Together)
HYBE's first group after BTS, TXT (Tomorrow X Together) leans into a more narrative-driven, concept-heavy approach. Their "Chaos Chapter" and "The Name Chapter" series explore themes of adolescence, identity, and belonging with a cinematic quality rarely seen in the genre.
NMIXX
Perhaps the most sonically adventurous group of their generation, NMIXX pioneered a song structure JYP called "MIXX POP" — blending multiple musical genres within a single track. Divisive at first, their approach has earned serious respect as the concept matured.
Why 4th Gen Matters Beyond Korea
Unlike earlier generations that broke through internationally after domestic success, 4th gen groups often build their global fanbases simultaneously with their Korean ones. Concert tours sell out in the US, Europe, and Southeast Asia within minutes. This generation isn't just exporting Korean pop culture — it's actively reshaping global pop.
Where to Start
- Pick one group that visually or sonically interests you and dive into their discography chronologically.
- Follow their official YouTube channels — most groups post full concert clips, choreography practices, and behind-the-scenes content.
- Join a fan community (Reddit, Weverse, or fan Discord servers) to get context for concepts and comebacks.
The 4th generation is still very much ongoing — new groups continue to debut and existing ones continue to evolve. There's never been a better time to jump in.
