Meet Bulletproof Stockings, New York's premier (and likely only) all-female Hasidic rock band. You won't find any male groupies at their shows because that is strictly forbidden by their religion.
You see, the Hasidic Jews do not allow mixed-gender socializing (also they don't allow women to have visible elbows or knees and they have to cover their hair with a wig once married among other rules). The fine promoters of Arlene's Grocery are pretty accommodating and will only allow women for their big show tonight. That's because the band went out and proved there would be an audience by selling some pre-sale tickets beforehand, according to the NY Post.
This is fascinating. In this AOL bio, the group says they are fine with only playing to women because there aren't any bands targeting just women. Actually this whole thing is mildly eyerolling:
Coincidentally, as a man, I am able to hear their music on their Facebook page just fine. I guess that makes Facebook non-kosher. All kidding aside, I think it's great that these women have a platform to express themselves.
