In “Lionel Popkin: Inflatable Trio” (above) at The Dance Complex, 536 Massachusetts Ave., Central Square, dancers perform on and around an inflatable plastic living room set, with comic elements of a family room repeatedly deflated, dismantled and reorganized by three dancers who are constantly upending – and upended by – the objects, people and situations that surround them.

“Unrequited” staged reading from 8 to 10 p.m. Friday at The Center for Arts at the Armory, 191 Highland Ave., Somerville. Tickets are pay what you can and sold at the door only, with $10 suggested donation.

Local playwright Andrea Aptecker premieres the ghostly gothic romance “Unrequited” with a staged reading directed by J. Deschene and starring Heather Hannon Ruff and Alex Hanscom. In the play, with hints of the kind of menace and tension stirred up in du Maurier’s “Rebecca,” Violet has married Douglas and moved into a sprawling old house, but she fears the shadows from his past that live within its walls (above, an image by Zlatko Unger via Flickr) and worries what will become of her when she uncovers the truth. Information is here.

Sixth annual Down Home Up Here Bluegrass Festival from 4 p.m. to midnight Saturday and Sunday at Passim, 47 Palmer St., Harvard Square. Tickets are $15.

Two days of  bluegrass and old-time music performances (above is Andrea Asprelli of Cricket Tell the Weather), with bluegrass-focused workshops throughout the weekend and a special Bluegrass edition of Club Passim’s Live Music Brunch on Sunday. Information is here.

Second annual Fan Fiction Theatre from 7 to 9 p.m. Saturday at Comicazi, 407 Highland Ave., Davis Square, Somerville. Tickets are $5.

While most fans never need to stray from pop culture’s official versions, others feel the urge to explore whether Hermione had more chemistry with Harry than with Ron or if the Justice League works better as a western – and this 18-plus night by the Ladies of Comicazi group includes plenty of unauthorized reimaginings ranging from sophisticated to the mortifying stuff written back in college with you and your friends as the X-Men (above, some X-Men cosplay by Kordite via Flickr).
