TOURS

Boston’s LGBT Past

This tour will take you around sites relevant to the LGBT underground in notoriously puritanical Boston, between 1840 and 1980, touching on figures like Henry David Thoreau, who’s widely believed to have been gay in sentiment if not practice, the gender-bending contralto singer-actress Charlotte Cushman and the innumerable forgotten names who created a thriving culture in bars, baths, coffee houses and private homes.

Sept. 16, 6 p.m.

THEATER

Significant Other

SpeakEasy Stage Company presents the latest play from Joshua Harmon (“Bad Jews”), prior to its New York debut. It’s about Jordan, a young gay man whose friends, to his increasing dismay, are getting married. Determined to find a partner himself, he sets off on a comically long and winding road to true love—or whatever approximation he might have to settle for.

Through October 8

Calderwood Pavilion, 527 Tremont St., Boston

Eight By Tenn

Zeitgeist Theater presents eight short plays by Southern gothic master Tennessee Williams, including “The Lady of Larkspur Lotion,” “Portrait of a Madonna,” “Auto-Da-Fe,” “This Property is Condemned,” “Something Unspoken,” “A Perfect Analysis Given by a Parrot,” “The Unsatisfactory Supper” and “Talk to Me Like the Rain.” SpeakEasy Stage did five Williams shorts in 2006, but all the choices here are completely different.

ART

‘Irving Penn: Beyond Beauty’

Despite Irving Penn’s importance in American photography, this is the first major exhibition of his work in the Boston area. Most famous for his celebrity portraits, Penn was prolific for years in fashion, portrait and still life, often publishing his work in Vogue magazine. “I can get obsessed by anything if I look at it long enough,” he once said.

MUSIC

Salim-Sulaiman

Brothers Salim and Sulaiman Merchant are among India’s most prominent commercial composers, with over 120 soundtracks to their credit in film and TV, plus dozens of pop songs and ad jingles. Even though their work is often in the background, they’ve become celebrities in their own rights—Salim was even a judge on “Indian Idol.”
