The girls in this knee-weakening Joe Sia collection of rock and roll groupies from the ‘60s and ‘70s may be nearing Social Security now, but back in the day -- wow! Example: the first in the bound volume of b&w photos and contact sheets -- a spaced-out young thing with a perfect body wandering a garbage-strewn Woodstock dirt road. Yes, being a rock star does have its benefits, and the girls here weren’t reluctant to show ‘em off in a variety of poses nude, semi-nude and clothed (happily, only a few of those), posed and candid, at rock venues public and private. We don’t know which ones found their way to Jagger, Stills, Hendrix, et. al., but any one of them could, in Mick’s words, make a grown man cry. All photos/contacts NRMT, though they’d seem so even if they weren’t.
