Tim Storms has the deepest voice ever recorded, being awarded a Guinness World Record title because of his unusual gift.
Storms was born in Tulsa, Oklahoma, and has been singing bass since the 8th grade, the artist's bio on timstorms.net
He was singing with a Christian a capella group, a few years ago, when an ear-nose-throat specialist remarked he can reach incredibly low tones.
After a check-up, Storms learned that his vocal chords were twice the normal size, giving him the ability to hit notes that only large animals, such as elephants, can hear.
Storms can't even hear himself singing when he reaches low frequencies, although he does feel the notes resonating in his head. They register as vibrations, more than actual sounds, but they do allow him to carry out a tune.
