The L.A. Times calls William "a shy young Texan with a powerful tenor," the Huffington Post describes him as "a tonic, a truly unique voice, a wickedly forceful personality," and the Wall Street Journal raves that he is "a blues and soul belter of uncommon skill with his piercing, full-bodied falsetto and dynamic attack."

William currently resides in New York City's Hell's Kitchen.
