Released in 2016 by Starship Entertainment, this EP serves as the powerhouse opening to the group's acclaimed 2.5-part "The Clan" trilogy. Transitioning into a more mature, dystopian narrative, Monsta X solidifies their identity as masters of dark concepts and heavy hip-hop influences with this release.
The Clan, Pt. 1 <Lost> showcases the group's versatility, blending intense urban sounds with surprisingly tender vocals. The album earned critical acclaim, peaking at No. 6 on the Gaon Monthly Album Chart and securing the prestigious "Disc Bonsang" at the Golden Disk Awards.
Key Tracks Include:- "걸어 (All In)": The high-energy title track featuring dominant synths, powerful swag, and a cinematic, story-driven concept.
- "Ex Girl": A softer pop ballad featuring Wheein of MAMAMOO, showcasing the group's "flower boy" charm and acoustic sensibilities.
- "네게만 집착해 (Stuck)": A fan-favorite B-side that highlights the group’s signature hip-hop choreography and performance power.
Whether you are a devoted Monbebe or a collector of K-Pop history, this album is a "precious gem" that captures Monsta X as they stepped into the mainstream global spotlight.
