Lim, who won first place in the novelty category, will perform a contemporary piece, "Toccata" by Emma Lou Diemer.
"This unique piece requires that he play inside the piano, which includes patting, strumming and other types of hand manipulations of the strings, in addition to the standard use of the keyboard," said Pro Art Musical Director James Arthur Gardner.
Chen won second place in the romantic era category.
Pro Art's "prodigy concert" features an irresistible line-up of young international, national and regional competition winners, all selected through a rigorous audition process.
"Kids" is the brainchild of Gardner and is sponsored, in part, by the Dr. Benjamin Spock Foundation. The final competition will begin at 7:30 p.m., Saturday, May 31, at the Lafayette-Orinda Presbyterian Church, 49 Knox Drive, Lafayette. Tickets (adults, $15; youths, $10) may be purchased at the door.
Former winners have gone on to play on the Late Night Show with David Letterman and at New York's Carnegie Hall. Audience members will also be treated to interviews of the young musicians and are likely to find they are well-balanced, normal kids. At the concert's conclusion, the audience will vote for its favorite performers.
All participants will receive engraved plaques, with cash awards for the winners.
