Around Town This Month

Sing without the karaoke machine. The holidays might be the only time of year when you can belt out a tune sans equipment and not feel like a warbling weirdo. Carolers-in-waiting can double their sing-along fun with the Los Angeles Philharmonic’s holiday classics program (Dec. 22, www.laphil.org) and the Los Angeles Master Chorale’s hallelujah-resplendent “Messiah” (Dec. 10 and 16, www.lamc.org).
