MUSIC: Legendary Bay Area hip-hopper, Too $hort, headlines The Labor Day Shakedown, a benefit to raise funds to cover the medical costs of a toddler from South San Francisco fighting a deadly form of cancer, along with a huge line-up of San Francisco-based rappers from the past, present and future. (10 p.m. to 1 a.m., Space 550, 550 Barneveld)

FILM: SF Film Society presents Film Socialisme, master filmmaker Jean-Luc Godard's latest work, which addresses "the decline of Western civilization—and its Babel-like confluence of languages—within the contexts of a polyglot cruise liner traversing the Mediterranean and, more intimately, an intellectual, loving family that runs a service station in provincial France." (4:30, 7:00 and 9:20 p.m., New People Cinema, 1746 Post Street)

ART: In the group exhibition, Avatars / Aliases / Alter-Egos, fifteen Bay Area artists who are all members of Gallery Route One, an alternative nonprofit art organization with a gallery in Point Reyes Station, are exhibiting work that explore "personal identity and the many ways of disguising, concealing and revealing oneself through distortion, substitution, masks and other strategies." (7 to 10 p.m., Gallery 1044, 1044 Larkin Street)
