Earthquake. Siyeon uses this single word to describe Dreamcatcher, a Korean pop group she's a member of. After hearing about her favorite lipstick shade and seeing Dreamcatcher's beloved goth aesthetic in person while we're backstage at KCON LA, no further explanation is needed.

Since debuting in January 2017, Dreamcatcher has undeniably shaken up the K-pop world with its nightmare-inspired aesthetic. Not only is Dreamcatcher a girl group eschewing the usual colorful, cutesy concepts, it also makes rock music. Don't believe me? Just watch Dreamcatcher's music video for "You and I."

Although K-pop encompasses various genres beyond pop, rock and girl groups rarely go hand-in-hand. The list of K-pop's rock groups is dominated by boy bands like CNBlue, FTIsland, The Rose, and Day6. But Dreamcatcher isn't trying to be a part of the boys' club. Its members don't go on stage with instruments like the aforementioned bands and couldn't care less if boys swoon over them.

Instead, Dreamcatcher is sending seismic waves through the K-pop world by seamlessly combining polished elements of a girl group with metal ones. Their electric guitar-zinged songs are complemented by intense-yet-sleek choreography, horror movie-esque music videos, and some of the boldest beauty looks you'll see a girl group try out.
