Reaction videos are great... when they're genuine. After Bohemian Rhapsody the movie came out, I think there were a lot of people out there claiming they had never heard the song before just to do a reaction.

I stumbled on this video earlier about a vocal coach listening to Pantera's Cemetery Gates. She is pretty impressed throughout the whole video, but if you want to get to the "mind being blown" part, just fast forward to 10:00. She does get a bit confused from pausing the song and thinking Dimebag's guitar is Phil's voice, but she eventually picks up on what is happening and is completely taken back by the end of the song when Phil's voice and Dimebag's guitar are mirroring each other, back and forth.

You can like whatever bands have come after Pantera, from the guys in Pantera, but this video only continues to prove that there was something very special musically with that band.
