Sisters Michelle and Andrea Baldwin are the driving -- and gyrating, wiggling and titillating -- force behind Burlesque As It Was, a performance group that revisits an era when stripping and erotic dance was an art form. Students of vaudeville and burlesque greats like Gypsy Rose Lee, the sisters and their sequined crew hosted a pair of performances this year: a Parisian-style cabaret and a saucy Valentine's Day fete. They've also been seen shakin' their saucy stuff at shows by bands like the Down-N-Outs. Forget Disco -- Burlesque As It Was takes retro to an entirely new level. Just don't try to shove a dollar bill down the side of the dancers' costumes, please.
