-- Bachelorette, 34: Oh the manic behavior of being on your 30s and still single. Check out Kara Herold's personal film about mothers, daughters, marriage, and being single. Starts at 8:30 p.m at Other Cinema at Artists' Television Access (ATA), 992 Valencia.

-- Diplo: Edgewater-born electronic genius (and the one who introduced MIA to the US) pumps out his work all over the dance floor along with Switch, Eric Sebastian, and Vin Sol at 10 p.m. at Mezzanine, 444 Jessie Street (at Mint), $20.

-- "Once More, With Feeling" (Buffy the Vampire Slayer): Aside from "Hush" -- which we think is the best episode, ever; in fact, one of the best moments in TV, ever -- this musical episode of Buffy ranks up there as a fan's favorite. (The reprise of "Under Your Spell" = sob!) Catch it tonight at the Bridge Theater, 3010 Geary.
