Like your music a little heavier than pop? Check out Dreamcatcher. While not quite k-rock or k-metal, the band’s backing tracks incorporate a lot of heavier-sounding guitar riffs and drum solos. I love the darker image that the band has, and it certainly sets them apart from the “cute” concept of other girl groups, or even the edgier “girl crush” concepts.
I’m just getting into them so I don’t have anything else to say, so take a listen!
