Pat Benatar

It's hard to overstate what a breath of fresh air Pat Banatar was in hard rock in the late 70s-early 80s.  Brilliant, straight ahead rock.  Very clean.  Her vocal range was very wide but strong everywhere, especially on the high end.  My favorite two songs of her many great ones are "Treat Me Right" and "Heartbreaker", both from the 1980 Crimes of Passion album.  Scintillating rock.
