Man With the Iron Fists was everything that I hoped a RZA-helmed kung fu adventure would be. That being said, I assumed that hearing Motörhead's "Iron Fist" in the score would be too much to ask for.
Kung fu metal is an untapped niche. There are more than enough horror-themed metal bands (White Zombie, GWAR, the Misfits), and some terrible sci-fi ones (anything that sounds like Fear Factory), but no metal band has incorporated martial arts into their music the way that the members of the Wu-Tang Clan have. Most likely, kung fu metal would end up sounding like the System of a Down and Tom Morello collabs with the Wu-Tang on the Loud Rocks comp. But hopefully, it would sound more like Motörhead.
Nothing conjures up action like Motörhead's music--one of the sharpest reviews I ever read compared Lemmy's tones to the sound that Snoopy's plane makes when he's fighting the Red Baron. The lyrics, like a kung fu movie screenplay, are just there to sound cool in the fray. "You know me, evil eye/You know me, prepare to die/You know me, you can't resist/Devil's grip, the Iron Fist" could be dubbed into Shogun Assassin. If Man With the Iron Fists gets a sequel, and it definitely deserves one, I'm hoping that RZA includes "Iron Fist."
