text:  That's Whitney Houston, number one. And what I love about the vocalists of yesteryear is no auto-tune. Right. And if you sound good a cappella, that's an a cappella track, then you know you can sing without any accompaniment, without any processing, without any auto-tuning, whatever. And the others I would mention would be, I always thought of the voice of an angel, Karen Carpenter. Oh, yeah. It was incredible. And, again, going back to the Frank Sinatra days, maybe Ella Fitzgerald was another great vocalist. Rosemary Clooney?
