I'm sure you're all familiar with the fantastic mid-90s military thriller Crimson Tide by Tony Scott and Jerry Bruckheimer starring Denzel Washington, Gene Hackman, James Gandolfini, Viggo Mortenson, and others.

I'm sure you're also familiar with its spectacular main theme, Roll Tide. If not, shame on you. Watch the video below to hear what you've been missing out on.

Done? Oh, you need to listen to it a few more times? No problem, I'll wait.

Ok, now take a few deep breaths and get ready for some more ear magic courtesy of Finnish metal group Nightwish. Those fine folks figured they liked Roll Tide so much, they'd play a portion of it live (mashed together with part of the theme from Deep Blue Sea).
