I have a sneaking suspicion this isn't the first time we're going to be talking about Beyond The Sons. The band is comprised of kids between the ages of 12 and 14, and whose introduction to the masses is now this absolutely killer cover of "Square Hammer" by Ghost. One listen and you're going to notice the fantastic vocal harmonies, the excellent playing, and even a few death growls in the background of some of the hits. Plus transcribing the keyboard parts onto guitar and bass is a cool touch!
Check out a few of their other covers here, including tracks by My Chemical Romance and Avenged Sevenfold. They're great!
