020416i-Dangrrr-Doll-burlesque

Aggregation No. 1The 10th annual Great Burlesque Exposition from Friday to Sunday, with shows each night, at the Hyatt Regency Cambridge, 575 Memorial Drive, in the MIT/Area II neighborhood. Prices vary.

Stop in at the expo ($15 per person) and shop for Valentines Day among the vendors, take a drop-in dance class and check out the art show, costume exhibit, and lingerie display and fashion show – but that doesn’t get you the real burlesque experience. For that, you’ll need tickets to the  the Rhinestone Revue of last year’s Howard Award winners (8 to 10 p.m. Friday, $35 to $55 plus online service fees); the intimate Bordello show with 15 top dancers (from 10:30 p.m. Friday to 1 a.m. Saturday, $35 plus online service fees); The Main Event, in which more than two dozen performers or teams compete for this year’s Howard Awards (from 8 to 11 p.m. Saturday, $35 to $45 plus online service fees); or the Sunday Showcase of rising stars and Sideshow Ball performers such as singers, jugglers, comedians and tap dancers (from 8 to 10 p.m. Sunday, $20 to $35 plus online service fees). Information is here. (If this all seems a little pricey and a lot too much, head instead to the Satanic Birthday Bacchanalia show from 8 p.m. Friday to 1 a.m. Saturday at Cuisine en Locale, 156 Highland Ave., Somerville, for spooky burlesque; drag; music by People Live Here and You Bred Raptors?; poetry by Jade Sylvan; circus arts performances; tarot readings by Madame Minoúx; and food and drink by Cuisine en Locale, all for $15. Not to mention the vegan goat sacrifice by an ordained satanic priest. Information is here.)

Aggregation No. 2Superhero storytelling from 10:30 to 11:15 a.m. Saturday at the Cambridge Winter Farmers Market, 5 Callender St., Riverside. Free.

Long before The Avengers dominated the multiplex, or even the comic book rack, there were people all over the world creating folk tales about creatures and people with extraordinary powers, and storyteller Diane Edgecomb knows them all. She’ll be enthralling kids (and probably others) with tales of Anansi, a spider god from Africa; Jabuti, the flute-playing tortoise from the Amazon rainforest; Princess See-it-all, with her X-ray vision, from Hungary; the Lord of the Cranes from China; and more. A free art project with the Kids Art Express follows from noon to 2 p.m., and the farmers market has local food, fresh produce and hot coffee for sale. Information is here.
