Sat., Feb. 23, Diego's Umbrella

The term “gypsy rock” brings up all sorts of questions. For instance: What is it? And is the word “gypsy” even acceptable for use by non-Romani people? I will only attempt to answer the former: Originally from Croatia, Diego's Umbrella is San Francisco's self-declared ambassador of gypsy rock, playing over-the-top tunes that meld Eastern European music—replete with accordion and tambourines—with punk-rock guitars and vocals, plus a little cabaret thrown in for good measure. Think Gogol Bordello plus Social Distortion plus Liza Minnelli. This is not bashful music, and it's probably best experienced with, say, some absinthe and a total loss of inhibition on the dance floor. 2708 J Street, www.diegosumbrella.com.
