THE SOUND OF MUSIC : Youths offer a fresh perspective on the masters.

Classical music belongs to the young this weekend and South Bay music fans should get their fill as the sounds of Beethoven, Mozart and Saint-Saens linger from Torrance to Palos Verdes.

First, the Torrance Symphony and the Torrance High School Wind Ensemble will share the stage of El Camino College’s Marsee Auditorium at 7:15 p.m. Saturday to present the fifth annual Family Concert, a free event designed to attract youthful audiences to symphonic music.

The Torrance Symphony will present the first half of the concert, performing a program that includes “Muzetta’s Waltz” from Puccini’s “La Boheme,” featuring soprano Mary Lou Basaraba; Saint-Saens’ “Rondo Capriccioso” featuring violin soloist Tamaki Kawakubo; and “The Man I Love” from Gershwin’s “Strike up the Band.”

John E. Hall, a trombonist whose credits include recording dates with tenor Placido Domingo and violinist Itzhak Perlman, will be guest conductor for the 50-member symphony.

The young musicians in the 34-member Torrance High School Wind Ensemble will perform the concert’s second half with a lively program that includes an arrangement from the film “Aladdin” and Gustav Holst’s “Second Suite in F.”

The concert is co-sponsored by El Camino College and the Japan Business Assn. of Southern California, South Bay Regional Committee, in cooperation with area schools.

Marsee Auditorium is at Crenshaw and Redondo Beach boulevards in Torrance. Information: (310) 329-5345.

The Peninsula Symphony Orchestra completes its 26th season with a performance Sunday that showcases the talent of 19-year-old violinist Jennifer Bai, 1993 winner of the Edith Knox Performance Competition. The concert begins at 7 p.m. in Rolling Hills Covenant Auditorium.

(Edith Knox, a celebrated pianist now retired and living on the Palos Verdes Peninsula, funded the youth competition with a $25,000 endowment about 20 years ago.)

Bai outplayed 18 other young musicians to win the final round of competition at the Torrance Cultural Arts Center in March, a performance that earned her the top prize of $1,000 and an opportunity to perform as a soloist with the Peninsula Symphony.

Bai’s skilled and spirited performance also captured the hearts of her audience. For the first time in the competition’s history, spectators voted for their favorite musician and Bai won her fans’ admiration and an additional $200.

Bai began violin lessons at a young age in her home in Shenyang, China. Her father, a children’s orchestra conductor, was her first teacher. In 1985, at about 11, Bai entered the Central Conservatory of Music in Beijing and in 1991 was offered a scholarship to USC School of Music.

Bai will perform her award-winning interpretation of Mozart’s Violin Concerto No. 4 in D Major, accompanied by the Peninsula Symphony.

In addition, the symphony’s program will feature Beethoven’s Lenora Overture No. 3 and Symphony No. 5 in C Minor, Op. 67 and Mozart’s Overture to “The Magic Flute.”

A members-only reception for Bai will be held after the performance. Admission to the concert is free. Admission to a 6:30 p.m. preconcert lecture on the program is $10 for non-members and $5 for members. The concert is sponsored by the Norris Foundation.
