YouTubers M Drako is one hell of a violinist and she's here to show the metal crowd her talents! Drako starts off her cover of Slipknot's "Unsainted" by sticking pretty close to the melodies at hand, and then goes off and really starts doing her own thing as the song progresses. It's awesome.
Drako's YouTube channel is full of covers of bands like Avenged Sevenfold and Lamb Of God. Check 'em out here.
