Trapped In The Closet Live. Yeah, the Slog and 3IG have already put this at the top of their recommendation lists, so this is less than original. But hey, people absolutely loved it last year. The Brown Derby Series got raves from the cracked hilarity of their tweaking of R. Kelly’s unintentionally intentionally hilarious hip-shlock-era. And if you miss it tonight, it also runs on Wednesday and Thursday. Like you’re going to miss it. (Re-Bar, 8pm, $12)

Richard Preston. The Hot Zone author turns his attention from the microscopic to the macroscopic — California’s primordial mega-trees — in his new book The Wild Trees: A Story of Passion & Daring. The excerpt I’ve read is fascinating. (Town Hall, 7pm, $5)

The Electric Six/Test Your Reflexes/Night Kills Day. Wikipedia describes the Electric Six as ‘”energetic” and “unique.”‘ I have no idea what that means, but they’re a Detroit rock band, and that usually means they can rock out with the best of them. PS to Neumo’s: No incense please. (Neumo’s, eveningish, $12)

El Dia de Los Ninos/El Dia de Los Libros. A celebration of children, families, reading and Latino culture emphasizing the importance of advocating literacy for children of all linguistic and cultural backgrounds. (South Park Library, free, 6:30pm)

Tyler Burnett Band/Daybreak/The Droneys. Just mentioning them because Tyler Burnett sounds like the love child of Tyler Florence and Carol Burnett. Heh. (Nectar, sometime tonight, $5)
