Travelers to Buenos Aires usually come back raving about the steaks, the culture and the nightlife in Argentina’s cosmopolitan capital. It’d be nice to take a trip down there, wouldn’t it? To soak in the theaters, the street art and the European-style architecture. Maybe do a little red-dressed tango in a back-alley club. But since a ticket to southernmost South America costs a hefty bit, the second best thing might be to go check out Los Pinguos, a band that uses Spanish guitars, a Cuban tres and a Peruvian box-drum to create sounds steeped in Latin rhythms. Los Pinguos play Friday, Oct. 19, at 142 Throckmorton Theatre. 142 Throckmorton Ave., Mill Valley. $20—$30. 8pm. 415.383.9600.
