Many have tried to cover the Dio classic "Holy Diver" and they've done a pretty good job, but this one takes the cake. From the vocals to the shredding guitar solos this is on point.
Oh by the way, THEY ARE KIDS! Yup you read that correctly. This is a family band named Liliac based out of Los Angeles. According to their website they are brothers and sisters. They are absolutely incredible musicians.
This isn't their first cover, either. They've got some incredible versions of "Crazy Train", "Enter Sandman", "The Trooper", and more. You've got to check out their official YouTube page.
