Mandy Harvey, the deaf singer who awed Simon Cowell and millions of viewers as a breakout star on America's Got Talent, will headline a series of concerts to benefit the hearing impaired who cannot access the life-changing hearing health care they need. The Hearing the Call Concert Series kicks off March 26th with a performance at the Fort Worth Community Arts Center's W.E. Scott Theatre. Tickets to the benefit event cost $40 and can be purchased online. The concerts will benefit Hearing the Call, a non-profit established by the Entheos Audiology Cooperative of practitioners to bring the gift of hearing to the impoverished afflicted in the United States and other countries around the world.
