Every year, Rob Scallon uses May to celebrate Metallica with May-tallica. He began this month with a crazy cover of "Master of Puppets" on banjo last week. This week, he kicks it up a notch, with his cover of the lead song from ...And Justice For All, "Blackened", on ukulele. Complete with guitar solo!

This guys plays a bunch of instruments, including guitar, bass, ukulele, drums, theremin, upright bass, and even shovel guitar.

Yes, he has a guitar made out of a shovel. It has one string, and EMG pickup, and he plays some crazy s*** on the thing.
