Not the best singing but it is Dave Mustaine, who's singing is odd and questionable. Guitars had a mid-90's Sepultura sound, ****ing awesome. Overall good cover, 7/10.

pretty good ... but the vocals and the solo almost sound like they are running in the background to the riffs ... but good job none the less ...

Pretty good. Only criticism I have has already been said, the singing could be better and the vocals and solo could be louder.
