Friday Happenings

The Whitehaus Family.

Whitehaus Family Records is an old-fashioned DIY music collective, and it's presenting a showcase tonight. The Whitehaus Family Equinox BLASTFEST features acts like Many Mansions, the Needy Visions, Lindsay Clark, and Brian S. Ellis: a useful index to Jamaica Plain's current indie music scene. Cambridge Family YMCA Theatre, 820 Mass. Ave., Cambridge, 5 p.m. $5-$10.

Mustaches

826 Boston, the do-gooder writing workshop has been running a Moustache-a-thon to raise money for its programs. More than 60 people have grown mustaches for the cause, and they'll be showing off their work tonight. If you're lucky, there may also be live mustache consultations. PA's Lounge, 345 Somerville Ave., Somerville, 8 p.m. Free.

Ethics

Princeton philosopher Peter Singer might be the best known utilitarian practicing in today's academy. His 1975 book Animal Liberation probably made more philosophers into vegetarians than any PETA ad ever has (even the naked ones). Tonight, he discusses his new book The Life You Can Save: Acting Now to End World Poverty. Just leave your deontologist friends at home and don't bring up evolutionary psychology, and you'll probably have a good time. Presented by Harvard Book Store. Brattle Theatre, 40 Brattle St., Cambridge, 6 p.m. $5.

Movies

Les plage d'Agnès, Agnès Varda's latest, is an autobiographical rumination that links the major events of her life and career to the beaches that inspired her. Ask her about it afterward; she'll be on hand. Harvard Film Archive, Carpenter Center, 24 Quincy St., Cambridge, 7 p.m. $10.

It's been too long since Bostonist has seen a Thai martial arts film, so we are geeked to see that Prachya Pinkaew, the director of Ong Bake, has a new one. Chocolate tells the story of Zen, an autistic martial arts prodigy who sets out to collect debts from corrupt gangsters. Brattle Theatre, 40 Brattle St., Cambridge, 11 p.m.
