Pulsing EDM and hip-hop flows come together in 24K, a K-pop outfit that stays on top of new musical styles. They've been charged up since debuting in 2012, the seven or so members tag-teaming rhymes and coming back together when the big, buzzy hook arrives. They zip over skittery trap-style beats on hyperactive squelchers such as “Hey You” and glide along with the electro-pop of “U R SO CUTE.” In whatever form, 24K give their all to each song, rapping and singing in energetic circles around the digital sounds.
