The Star-Spangled Banner

After all these years, still surprising, still so cool.

South of the Grapevine

Outstanding...almost. The parts that work are pretty great but the riff really needs to move to another chord when Marvin does for it to have really taken off. Then again, that's just life in the mashup world, and it does add a certain tension. (Since both these songs are oh so lacking in tension.)

Actually, I think the section with the backing vocals is the most effective. Still, if nothing else, it highlights that a voice like Marvin's seemingly works irrespective of genre or context, and illustrates the obvious yet (these days) easily overlooked blues roots of metal.
