The kid band Motion Device are one talented group! 10-year-old singer Sara is even dressed just like Ozzy Osbourne with a white fringe-sleeved shirt, a huge cross on a necklace, and those famous round sunglasses. Meanwhile, the bass player's leather get-up may not appeal to Geezer Butler's vegan lifestyle, but she certainly brings the metal!

Vocalist Sara nails all of the Ozzy-isms in her singing, taking this cover to the next level. She seems to lose herself in his personality as this cover becomes ever-more convincing. The rest of the band do a great job as well, taking on one daunting song and doing an excellent job at it. Motion Device must be one fun band to see play live!
