“Restructured” opening reception from 6 to 8 p.m. Friday at the The Nave Gallery Annex, 53 Chester St., Davis Square, Somerville. Free.
More than 50 artists – a work by Megan Potoma is above – explore what “feminist art” means today, especially when looked at in the context of a history filled with controversy, turbulence, progress (the movement of the 1970s is often viewed as utopian, sometimes naïve and even exclusionary) and backlashes (the 1980s brought a backlash against feminism and feminist art that curators Boriana Kantcheva and Micah Eglinton-Woods say can be felt even today). After this opening reception, the exhibit can be viewed during gallery hours through Dec. 16. Information is here. (This is also the weekend of open studios at Brickbottom and a Pop Up Gallery/Silent Auction of Lesley University artists on Friday, as well as a good time to see Le Laboratoire’s “The Long Now,” which looks at stretching out time, including via The Clock of the Long Now. All are free.)
International Pop Overthrow music fest from 7:30 p.m. Friday to 1 a.m. Saturday and from 7:30 p.m. Saturday to 1 a.m. Sunday at P.A.’s Lounge, 345 Somerville Ave., Union Square, Somerville. Tickets are $10 each night.
Seven bands perform nightly at IPO, a four-day music festival (it began Wednesday) devoted to power pop and related genres. It’s not a Boston thing – it began 18 years ago in Los Angeles and has spread to more than a dozen cities internationally – but we do it pretty damn well. (The band Powderhouse is seen above.) Information and a complete schedule is here.
You Gotta Be KidNME! family and children’s concert from 1 to 2 p.m. Saturday Granoff Music Center at Tufts University, 20 Talbot Ave., Somerville. Free.
