If you search "CLC Hongdae" or "Cube Girls Hongdae" you can see many different songs that they have done live. You can find plenty of fancams of your favorite members too. They have been doing this for a really long time most every week. No one can say they don't know how to sing because they have been doing it live and unfiltered over and over again, again for charity. If you are going to hate on CLC it will reflect more on you than them. These girls are great and I think there will be a lot of wonderful things in their future.
