A young lady named Linzey Rae with a great Metal voice has a YouTube channel where we can enjoy her grunts on the mic over some Metal songs. At first I thought it was some lip syncing. As we can see with some further searching, she sings in a Metal band known as The Anchor.
I don’t know where she gets her guts to sing with such a voice but I find her quite amazing.
Checkout this video where she sings and cooks for us a Shepard’s Pie:
You’ll find some info on The Anchor band on their Facebook page and on her YouTube channel:
