“Glengarry Glen Ross” is dark. A corporate greed, arrogance and desperation-kind-of dark. But the David Mamet play, in all of its darkness, is worth grappling with. And it will definitely make you feel better about your own job. The Swinging Hammer production is 7:30 p.m. Thursday to Sunday at Grange Hall.

No, Steve Martin is not here, most regrettably. But next best thing: We’ve got his farcical state of mind. Bainbridge Performing Arts presents “Picasso at the Lapin Agile,” a play featuring unlikely chumsters Albert Einstein and Pablo Picasso, in a bar, on the brink of ingenuity. Friday/Saturday, 7:30 p.m. Sunday, 3:30 p.m.

In some ways, it feels like the dead middle of October: that pumpkin bounty, the encroaching rain, those fire hydrant leaves. But the First Friday Art Walk reminds us we’re just at the beginning, as artists come together to celebrate a new month and new pieces. Michael Pontieri’s “views of utopia” (Bainbridge Performing Arts) is particularly disarming. We’re also a fan of Virginia Paquette’s watercolor and collage series (the Island Gallery), her visual response to the music of her husband, Bill Smith, and their years together in Italy. The BPA Gallery reception is 5 to 7:30 p.m., the Island Gallery reception, 6 to 8 p.m.
