Adam Roth is like a human digeridoo. The 28-year-old "Sound Healer" doesn't wear shoes and walks on public streets and American Idol stages. Although he has a booming deep voice that radiates through the body, when he sang "Hallelujah" for his audition, it was much higher and sounded pretty and sweet. It touched a different chakra than his booming sounds. Keith said his voice is beautiful but he uses it schizophrenically. Adam explained that he's just trying really hard because this is so important to him. Dr. No turned him down, Jennifer said yes, and Adam's sound therapy caused Keith to hand him the final ticket of the day.
