Monday

bullet-gray-small Robin Cook and Daniela Lamas read from 7 to 8:15 p.m. at Harvard Book Store, 1256 Massachusetts Ave., Harvard Square. Free. Cook, author of genre novels such as “Coma,” combines flu, an organ transplant black market and cutting-edge CRISPR gene-editing technology into the thriller “Pandemic,” while Lamas (pictured, by Beowulf Sheehan) is a critical care doctor at Brigham and Women’s Hospital (and on the faculty at Harvard Medical School) whose nonfiction “You Can Stop Humming Now” looks at what happens when medical science extends patients’ lives for days, months or years beyond what’s expected. Information is here.


Tuesday

bullet-gray-small Trash Night Video: “Munchie Strikes Back” from 7:30 to 10:30 p.m. at The Brattle Theatre, 40 Brattle St., Harvard Square. Tickets are $8. This monthly film event lovingly selects and screens cinematic trash, and “Munchie Strikes Back” is that – an inept 1994 kid’s film that these days we’d suspect was written by AI, from the teen romance to the sports redemption story to the mom’s sleazy boss (mom is Lesley-Anne Down, eliciting sympathy for the path she traveled since “Upstairs, Downstairs”) with an unconvincing and supposedly wacky imp character all puréed into a film in which “a goodly portion of the appeal” is spotting how many times the cinematographers allowed the board Munchie is nailed to into the shot. Information is here.

bullet-gray-small Great Molasses Flood from 8 to 11 p.m. at Club Passim, 47 Palmer St., Harvard Square. General admission is $20. This Iguana Music Fund-winning project takes place on the 100th anniversary of a strange and dark day in Boston’s history, with the eponymous quartet recording a live album of songs about an actual fatal flood of molasses with readings from Stephen Puleo’s “Dark Tide,” the preeminent book on the subject. Information is here.


Wednesday

bullet-gray-small January Dispatches: Boston Sci-Fi Film Fest Best of Fest 2018 from 7:30 to 9 p.m. at the Somerville Theatre, 55 Davis Square. Tickets are $11.

bullet-gray-small “Othello” from 7:30 to 10:30 p.m. (and playing through Feb. 9) at the Loeb Mainstage, 64 Brattle St., Harvard Square. Tickets are $25 or $55. This tale of fatal bigotry and xenophobia from Shakespeare, via an imported (and acclaimed) production by the Oregon Shakespeare Festival and director Bill Rauch. It’s been playing for a while and continues for a while – but most performances already have either limited seating or are already sold out. Today’s performance is considered more open than most by the box office, but that’s not saying much. (Look also at seats from Saturday to Jan. 24.) Information is here.


Thursday

bullet-gray-small BCMFest of Irish, Scottish, Cape Breton and other Celtic music from 7 to 9 p.m. and 10 p.m. to midnight (and continuing through Sunday afternoon) in Harvard Square. Tickets are $10 to $25 and sold by different venues, depending on the show. The area’s twice-annual homegrown celebration of Celtic music and dance marks its 16th year, with dozens of performances over the course of a weekend – including a Dayfest with 12-plus hours of music Saturday – at Club Passim, 47 Palmer St.; the Atrium on the fourth floor of 50 Church St.; and at The Sinclair, 52 Church St. The weekend includes workshops as well as performances. Information is here.

bullet-gray-small Cracker and Camper Van Beethoven play at 7 p.m.in The Middle East Downstairs, 480 Massachusetts Ave., Central Square. Tickets are $22 in advance or $25 on the day of the show. This is annual now? These linked bands made the 1980s and 1990s tolerable for a certain kind of person – in large part, the smart-asses among us – but there’s no denying they produced some classic songs hitting notes from Southern to psychedelic, such as “Take the Skinheads Bowling,” “Low” and “Euro-Trash Girl.” The bands each get sets in a classic Cambridge music venue, just like last year at this time. Information is here.

bullet-gray-small “The Scarlet Ibis” opera from 8 to 10 p.m. (and continuing through Sunday) at the Longy School of Music, 27 Garden St., Harvard Square. General admission is $25 to $35. The Boston Opera Collaborative presents the local premiere of an opera based on James Hurst’s short swampland tale about Doodle, a boy with disabilities whose older brother pushes him to be “normal.” Puppetry and a minimalist but lush score performed with a nine-piece orchestra add to the exploration of notions of physical limitations and mystical otherness. Information is here.


Friday

bullet-gray-small James Geary presents “Wit’s End” from 7 to 8:30 p.m. at Porter Square Books, 25 White St., Porter Square. Free.
