The archetype for the '60s-era girl group was etched indelibly into stone, like a commandment: three pretty girls with matching outfits and bouffant hairdos would sing, with musical backing supplied by a bunch of guys standing in the shadows. The Quatro sisters shattered that archetype forever with the Pleasure Seekers, an all-girl teenage rock & roll group who played all the instruments themselves and were fully capable of wiping the stage with any male band that crossed their path.
