For those of you who think hair metal is a mindless musical genre created by unskilled, self-indulgent degenerates, Jim Gillette of Nitro is here to prove you wrong.

In his wildly popular instructional video Vocal Power, which has sold thousands of copies in each year since its 1991 release, Jim gives practical tips for garnering the glass-shattering voice of your dreams (all in the comfort of your own home!).

Unlike many of his notorious counterparts, Jim is an advocate for a healthy lifestyle—eat right, get plenty of sleep and lay off the drugs, man. Just look at those quads—seriously nice teardrop, Jimbo!

If you want to harness the power that it takes to accomplish a six-octave range like Jim’s, stuff a sock in your pants and start practicing. With hard work and dedication, you can be a rock star, too.
