I admit, I’m biased — I think Pat Benatar has one of the truly greatest voices in rock music history. Her flexibility and range are phenomenal, and her power is simply amazing.What I like about this collection is that it shows off many of the sides to this spectacular talent. For those who think of Ms. Benatar as just a “rocker-chick,” this set will show you things you might not have encountered otherwise. Diverse would be a good one-word summary of this set.The hits are well-represented here, along with some great album tracks, but this set also brings together quite a few rarities — demos, songs from soundtracks and other collections, and some unreleased songs. Not all the material is of the caliber of “Promises in the Dark” or “Love is a Battlefield,” but Pat shines on each and every track.For fans of Pat Benatar, this is a must-own set. Even the casual listener will find this set quite complete in its selection of songs they’ve heard on the radio, although with quite a bit of other stuff tossed in. If you’re only after the hits, I’d suggest you go with one of the single-disc hits collections, but if you’re interested in the diversity and scope of Pat Benatar’s career, this is the set to buy.
