She may sing and just not be well known for it?

Actually when I first saw the trailer I kind of thought she was in more of a competition, perhaps a school event. though now I look back and a concert seems quite plausable.

She may just sing just not as a profession, also you don't need to be a well known performer to have decent crowds.
