Yeah, Kim Bo Kyung (aka Stephanie Kim formerly member in CSJH The Grace), her newcomer in krock music (maybe rock ballads genre suitable for her genre).
I think max what she can be in my book, is pop rock singer, her voice is nice but doesnt have that unique personality, without it is hard to become rocksinger without band. Now she is very strongly influenced by other performers and havent find "her own voice" jet.
But she still is starting her career, so time shows does she falls deeper into kpop or rises to krock. LAst choice is hard one bc in korea rock isnt popular genre and recording companies doesnt support rockmusicans bc of this.
It seems not many people are interested in rock. I usually prefer alternative rock, even pop rock but I don't refuse even hard rock if I enjoy the rhythm.
I listen to : CN Blue, F.T. Island, Sinawe, Cherry Filter, GUYZ, PIA. TRAX was also great but since No Min Woo and then their other member left they changed their style. I'm actually more into J-rock, from visual key to hard rock, Japan has more bands to offer.
