Hmm..I forgot about her..I have to admit I'm not that familiar with her head voice; whenever I study her I'm usually so enthralled by her belts that everything else seems mundane in comparison. lmao..any nice clips you can post?
Her head voice specifically I can't think of any performances that truly showcase it fully, this video however showcases her voice fully
So the only formidable receipts posted to the contrary belong to a South Korean gospel singer...I think the naysayers kinda made the OP's case for him.
