's second EP,
Fe3O4: Break
, follows in the same vein as its predecessor,
Expérgo
, providing fun, throwback vibes that take a kitchen-sink approach to genre with exciting results. They dabble in Jersey club trends ("Passionfruit"), tackle big bass (the aggressive "Boom"), adopt some Wild West country flair ("Run for Roses"), and hit the dance-friendly pleasure center on the funky "Dash." Stadium-sized single "Soñar (Breaker)" veers closest to the "expected" K-pop sound, blending a huge group chorus, popping beats, and familiar hip-hop nostalgia to maximum effect, just as "Break the Wall" does the same with shimmering synths. Upon release, the set topped charts in South Korea and the U.S. ~ Neil Z. Yeung
