Fourth of July Celebration at the Jarvis Conservatory offers an evening of spontaneity and fun — and the fireworks of great singers. At this special Saturday Night Opera, during the intermission they’ll offer complimentary champagne and tapas.

As always, it’s always a surprise to see what singers will show up to sing their favorite arias.

Accompanist is Kristin Pankonin.

Andrew Moore leads an audience sing-a-long, and accordionist Lou Zanard will charm the crowd during intermission. 

The singers who show up take the stage with sheet music in hand when called by the pianist.

Vocalists who come to the Conservatory from around the Bay Area for Saturday Opera Night range in experience from student to diva.

Ticket prices are $15 per person and available at the door on the evening of the event.

The house opens for general seating at 7:30 p.m., and the singing starts at 8.

The Jarvis Conservatory is at 1711 Main St., Napa, For further information, call 255-5445.
