Jaime Vendera
From Wikipedia, the free encyclopedia
Jaime Vendera is a rock singer and voice coach. He is the first documented man to break a glass with his voice without amplification. He achieved this while testing the myth 'Can a singer really break glass with just his or her voice?' in an episode of the MythBusters television show on Discovery Channel. His vocal range spans six octaves.
He is the author of two books, Raise Your Voice (ISBN 0-9749411-1-5) and The Ultimate Breathing Workout (ISBN 0-9749411-4-X).
