SEE INSIDE STEVEN TYLER’S VOCAL CHORDS (PLUS-SIZED LIPS SOLD SEPARATELY)

Our buds over at Idolator have posted a fascinating video from National Geographic’s Incredible Human Machine TV show, featuring in-throat video of recent surgery performed on the Aerosmith singer’s vocal chords. Watch as some ruptured blood vessels on the vocal chords get zapped away by lasers in mere seconds, and then view his vocal chords gyrating in real time — post-surgery — as the singer belts out “Dream On.”

Sadly, National Geographic doesn’t explore the anatomy of Tyler’s humongous lips.

View the video here.
