The music of Argentina has always maintained a sense of mystique in the United States. Its heritage is preserved by bands such as Octango, which will be the backing band for Boccatango, a contemporary tango-dance performance that surely will evoke countless spasms of the hips and buttocks in its audience members. Even though this is a seated event, if you’re not causing too much damage to the Mondavi Center’s seats, dancing in the aisles may be encouraged. Songs from both Astor Piazzolla and Carlos Gardel—two of Argentina’s greatest exports—will be incorporated into the soundtrack. Boccatango visits the Mondavi Center on Tuesday at 8 p.m. Tickets range from $16 to $42, and all ages are welcome. Speaking the language is not necessary. Allowing yourself to enjoy the spectacle is.
