The Fall music season has been launched in orbit with a glitzy gala at the Symphony. This week continues with classical music galore: the other heavy hitter, the SF Opera introduces his new music director, Nicola Luisotti, in Verdi's Il Trovatore, tonight. The all-star cast includes Dmitri Hvorostovksy, Sondra Radvanovsky and the comparatively simple to spell Stephanie Blythe in a story that makes Harry Potter look realistic. We don't go to the opera to watch reality tv, and the arias are sublime. You can check for yourself, for free, at a live simulcast of the War Memorial Opera House performance on a giant screen at the AT&T ballpark on Saturday, September 19th. Also, you can get the pupu platter sampler of the upcoming season, also for free, zilch, zero, nada, with the traditional Opera in the Park concert. Please arrive early, it gets really crowded on the Sharon Meadows lawn, and you don't want to miss SF Chronicle's editor-at-large Phil Bronstein's unintentionally hilarious attempts at a stand up comedy routine, if he's MCing again this year.
