This is cool as shit dude, I like the guitars a lot (snare not so much, everything else is fine) - never heard the original song, and I can't deny this is not what I was expecting of the band haha; the main riff pretty much sounds like a tribute to
Is this a song from earlier in their (MDB's) career? To me it has more a of a bluesy doom rock feel, rather than doomy/morose/somber metal (maybe I'm confusing MDB with Paradise Lost?)
Anyway, again, great job!
