I hate that everyone uses this video for reference in regards to Demi’s vocals. You should look up Demi’s Tik Tok performances- Dancing with the Devil, Tell me you love me, The Art of Starting Over. Or their live performance of Monsters by All Time Low ft Demi.
You should check out Demi’s song anyone on the Grammys and her live preformance of Father. Demi definitely has a better preformance of that last song (Remember December) but you saw the video it isn’t meant to be that toned down
