Building A Better Dave

I saw a band open for Ozzy I had never heard of, and MAN WERE THEY HEAVY. I immediately went out to buy their album.  There was only one problem. My ears could not comprehend what I was hearing. At times it sounded like someone making fun of heavy metal.  It was so fast and the guitar solos sounded like a fax machine in heat. Metallica's Ride the Lightning was like nothing I had ever heard before.
