Although Chanyeol's vocal keeps in the background because of the high-level vocals in EXO, I think his voice is better than the vocal members of many average groups. I wouldn't be surprised if he made his solo debut with ballad songs while singing with his guitar which suits his well... Check out his Wind Of Change and Creep performances:
Maybe because of the prominence of Bobby's powerful rap that competes with even underground rappers, many are not aware of his vocal potential. Whereas, he also showed that vocal fabric in his solo album. His husky voice suits the songs very well:
Most kpop followers know that SM's vocal training is qualified. Even the rappers of groups have basic vocal skills. But some of them stand out a little bit more about it, Amber is one of them. The covers she made are very successful in terms of singing:
CL, who is one of the first names that come to mind when it comes to a female rapper, has a strong vocal. Apart from rap, she also has vocal parts in many solo&group songs:
Ravi, one of the idols have more than one string to fiddle, is actually an ambitious rapper, but also has good enough vocal to show the courage to sing live in such program which many vocals hesitate to participate in.
X1 & VICTON's Seongwoo
Seung Woo, who attracted much attention with his vocals in Produce X 101, was actually the rapper of the VICTON. Everyone, who learned that he was a rapper, was quite surprised because most people considered him vocalist throughout the competition. His position in X1 was vocal tough ^^
Dong Woo is one of the rappers who will surprise you with his vocal. When the panelists listened to the high-notes he made, no one could even think that the person behind the mask was a rapper:
MONSTA X's Jooheon
Monsta X is one of the groups popular with rap-line, but who would say that the rapper's vocal is no joke:
X1 & UNIQ's Seongyoun (Woodz)
Seungyoun, who we know from SMTM and Produce X 101, is actually the main rapper. But in the survivor program, he surprised us with his strong vocals. There are also many songs he covered on his YouTube channel. Woodz' is also a talented producer.
Each group's rapper can attempt to sing a little, but I think the rappers above have serious potential about vocals. Which rappers surprise you with their strong vocal?
