Being able to belt out a tune like Adele or Pavarotti is not just about raw talent. The best singers in the world have to work on their technique—like how to control their breath and develop the stamina to hit note after note for a two-hour concert. But pop stars and opera singers aren’t the only vocalists who have figured out how to harness their voices for maximum impact.

Death metal vocalists also train their voices to hit that unique guttural register. And those iconic screams are not as easy to master as they might seem.

Vocal scientists at the University of Utah are now bringing death metal singers into the lab to try to understand how they make their extreme vocalizations. What they’re finding is not only insightful for metalheads, but might also help improve treatment for people with some types of vocal injuries.

Host Flora Lichtman talks with Dr. Amanda Stark, speech pathologist and vocology researcher at the University of Utah, and Mark Garrett, vocal coach and lead singer of the band Kardashev.
