I could only wonder at the maintenance requirements on this hairdo... That's not just a beehive, that's Utah in there!
I also notice that the vast majority of these come from the late 60s/1970s... a time period not known for its good fashion sense. In 30 years, will someone be able to do the same for this time period (assuming anyone is releasing album art anymore)? Also, most of these bands are not exactly stadium headliners (the aforementioned WASP album cover being the exception). Most of these poor schlubs couldn't afford decent photographers and stylists.
