Father Gordon Kalil calls it “a great witness of the community coming together.” Those who’ve attended Armonia concerts in the past know the event is also great entertainment.

The annual benefit concert and gala takes place Saturday at the Napa Valley Opera House, and once again it taps the superb talents of international artists to help local kids.

Soprano Mónica Ábrego and tenors Marco Antonio Labastida and José Medina will present “Romantica,” an afternoon of music ranging from Broadway hits, multicultural love songs and zarzuelas to opera arias.

It raises funds for the St. John the Baptist Catholic Church Youth Outreach Program, a bilingual effort that serves more than 3,000 teenagers in the valley, “and it grows every day,” Kalil said.

Labastida and Medina, who have performed in Napa since the first Armonia concert in 2001, both take considerable time from their thriving careers to help young people.

Labastida, a graduate of the Oberlin Conservatory of Music, performs throughout Mexico, the U.S. and Canada, with a musical repertoire that includes zarzuela, opera, traditional Mexican music and bel canto. He is also the executive director of the Tijuana Youth Symphony.

Medina, who made his professional debut as Rodolfo in “La Bohéme” with the New York City Opera, has also performed in Europe, Mexico and throughout the U.S. He is artistic director of the Tijuana Opera in his hometown.

No one who saw Medina’s first appearance in Napa, at the first Armonia concert featuring three tenors from Mexico, will forget Medina’s most memorable moment — when he dropped a handkerchief on his head and warbled the soprano part in “The Drinking Song” from “La Traviata.”

With the addition of Ábrego to the bill, there is no longer a need for Medina to reach those high notes. Ábrego, who also comes from northwestern Mexico, studied at the Baja California Music Conservatory and the Manhattan School of Music. She is a member of the Pacific Opera Company.

The artists create a “joyful occasion,” Kalil said, “an exquisite musical experience that brings us together to celebrate our richly diverse cultures … Art for art’s sake is wonderful — but art for the sake of youth is truly a gift for us all.”

Kalil also had high praise for the “community leaders, business partners and volunteers” who are supporting Armonia. He noted that the more than 150 Napans who are donating their time and talents to produce the Armonia event include honorary co-chairs Margrit Biever Mondavi; Sal Renteria, founder of Renteria Vineyard Management, Francis Ortiz-Chavez, artist, president of the Napa Hispanic Network and a member of the Napa Valley Unified School District board; and Angela Peatman, chairwoman of Cope Family Center’s Family Circle and a tireless volunteer for many local nonprofit organizations.

Youth leaders Luis Juarez, Nicole Waechtler and Jose Carrasco are also lending their time and energy to the production.

“Romantica” begins at 4 p.m. on Saturday at the Napa Valley Opera House. The gala luncheon at Uva Trattoria is sold out, but tickets are available for general admission at $40, which includes a sumptuous intermission spread of hors d’oeuvres and wines to taste.

Tickets are available through the Opera House box office or by calling 226-9370, ext. 13. For more information, visit www.ArmoniaNapa.org.
