A YouTube user who goes by the name Rob Scallon is a genius when it comes to string instruments. His latest accomplishment was with an instrument we thought would never have a hard sound. He managed to do a cover of "War Ensemble" by the thrash icons, Slayer.

His performance clearly shows that a Ukulele can sound furious and also have a classical rhythm. Rob managed to master the cover with an instrument we thought would be impossible.

Watch this Ukulele bust out with some fierce sound playing a Slayer cover!
