Fourth Annual Harvard Square Salsa Sampling and Latin Beats Dance Party from 7 to 10 p.m. Friday on Brattle Plaza, Harvard Square. Free.

Take a dance lesson and salsa the night away to Latin tunes from DJ D. Martinez, as well as sipping mocktails from Beat Brasserie and sample chips and a variety of the other kind of salsa from Harvard Square restaurants such as El Jefe’s Taqueria, Charlie’s Kitchen and others. Information is here.

“Marina” historical drama at 8 p.m. Friday and Saturday and 4 p.m. Sunday at the Massachusetts Institute of Technology’s Kresge Little Theater in Kresge Auditorium, 48 Massachusetts Ave. Free, but tickets are first-come, first-served; reserve here and arrive 15 minutes before a performance to claim seats.

While adapted from Shakespeare’s “Pericles” and telling the tale of a child born on a storm-tossed ship, a princess abducted by pirates and enslaved in a brothel, and a long-lost daughter reunited with her parents, the story of Marina, princess of Tyre in ancient Greece, also acts as a preview of a new nonfiction account of Marina’s life by narrator professor John Gower. The show is also meant to interrogate how our stories are shaped by those who tell them, in Marina’s world and in ours. Information is here.

Haley Bryant outdoor concert from 3 to 4 p.m. Sunday on the East Lawn at Longfellow House, 105 Brattle St., West Cambridge. Free.

Texan Haley Bryant is a second-year student at the Boston Conservatory at Berklee and an extraordinary soprano – and she and fellow students will present an afternoon of songs and arias, part of a summer of free events, some more connected to the house’s role in history (i.e., as Gen. George Washington’s headquarters) than others. This one is just a sunny day listening to music on a lawn, and visitors are encouraged to bring chairs, blankets and picnics. Information is here.
