Hello SambaGuitar, thank you for your introduction and welcome to the forum.
Maybe you can post some music that you recorded
As you are a part-time musician and you worked with many great talents I'm interested what you think about the voice of this young lady.
Here are two download links (same song):

What's your opinion? I think she is very talented. If you listened to this song we will tell who she is
