Idolator

As teased here Friday, Steven Tyler appeared on the National Geographic Channel's Incredible Human Machine last night, and the results were pretty incredible, in a "holy crap, all those tendons and goo are inside me, too" sort of way. Actually, what's even more amazing to watch is the first half of the clip, during which the wizened Aerosmith singer's inflamed blood vessels in his voicebox—the rupturing of one forced the postponment of some tour dates last year—get zapped away by a laser in such a zippy way, I seriously thought I was watching someone play around with Photoshop at first.

This morning, Steven Tyler and throat surgeon Dr. Steven Zeitels appeared on Today to promote their Sunday-night appearance on the National Geographic Channel's Incredible Human Machine; if you ever wanted to know just what happens to the insides of the Aerosmith frontman's throat when he hits that high note in "Dream On," then this is going to be the show for you, as the program will reveal the stretching and straining that Tyler's vocal chords undergo during the course of a show. Appetizing! I only wish they'd recreated the vocal-chord-cam live, as I'd love to see what his innards looked like when he squawked that high note at the 0:58 mark. Aspiring vocalists, remember: Warming up is very important.
