Print San Diego Opera returned to the Pechanga Arena parking lot over the weekend for a spring festival with a pandemic-themed recital and a colorful production of “The Barber of Seville.” The festival — which continues with three more performances of “Barber” this week — takes place in the same spot as the company’s last drive-in opera last fall, “La bohème,” but it improves on the formula. This time there’s better video screen placement, more live close-ups of the singers, a performance area that expands beyond the stage and the ability for audience members to view program notes and English translations on their cellphones mid-show. Artistically, it’s a feast for the ears, with many fine vocal and musical performances.
