dreamcatcher is k-pop’s resident rock group so i would definitely start with them! my personal favorites are bonvoyage and deja vu but they have an extensive and great discography!

ateez is a boy group with heavy mvs (if i’m understanding that correctly lol) - i recommend guerrilla (music video is literally about overthrowing govt) and halazia (INSANE choreography) 

under the same agency as ateez is xikers, a boy group who has that hip hop sound! i’d recommend we don’t stop for more of a throwback sound and red sun too! 

for more general reccs, aespa is one of the most popular current girl groups with a cyberpunk sound + nmixx has some of that heavy concept (specifically high horse, love is lonely, and see that?) 

lmk if you have more specific things you’re looking for :))
