Amythyst Kiah is a Southern Gothic, alt-country blues singer/songwriter based out of Johnson City, TN, which has been her permanent residence for nearly a decade. She has been performing in what is known as the Tri-Cities (Bristol, TN/VA, Johnson City, TN, Kingsport, TN) and in various parts of Southwest Virginia.
