Twenty-one talented students are vying to make the “Top 10” cut and a chance to perform before an expected sellout crowd at Benaroya Hall on May 21.

One of the contenders is 11th grader Oliver Aldort of Eastsound. He plays the piano and cello and conducts.

The public can cast an online vote by viewing and rating the video entries at www.king.org to help determine the winners of the KING FM Ten Grands Young Artists Awards competition. Online voting ends at 4 p.m. on Friday, April 2.

A panel of judges selected the “top 20” finalists for the public vote phase, narrowing the field from 170 video entries. The grand prize winner will receive a $1,000 scholarship and invitation to perform alongside the featured artists at the Ten Grands concert on May 21. Other finalists will also perform at the musical extravaganza, which benefits the Snowman Foundation and its mission to “give the gift of music to children.”

The third annual Ten Grands Seattle concert showcases some of the Northwest’s most accomplished musicians. Ten concert pianists will play simultaneously, as soloists and in various combinations. The “something for everyone” concert on May 21 includes classical, jazz, blues, gospel, boogie woogie, pop, tango and contemporary music, according to Michael Allen Harrison, artistic director and founder of Ten Grands and The Snowman Foundation.

Bellevue resident and longtime music educator Kathy Fahlman Dewalt, the executive producer of the Seattle concert, said the inaugural concert in 2008 and last year’s event have generated more than $70,000 in grants funds. Seventeen groups in Washington state have received financial support of their musical activities and programs, including organizations that provide access to music to under-served and economically disadvantaged children in several communities.

RBC Wealth management is the presenting sponsor for the 2010 Ten Grands concert in Seattle.

Tickets, priced from $42 to $120, are available at Benaroya Hall Ticket Office, www.benaroyahall.org or 206-215-4747.
