NewComer Chorus Battle, also known as NCCB is a YouTube chorus battle event held in 2013. It started on April 22, 2013.
However there is no prize as this event is for the sake of fun and promoting newcomers - YouTube singers, mixers, animators and artists - and to create a fun event for the community. There are no judges as everything will decided by the audience voting for their favourite groups.
