The Charleston Symphony Orchestra is bringing concert-goers the music of the original live-fast-die-young rock stars: Mozart and Mendelssohn. The Young Geniuses concert will feature music written early in their careers, to showcase the amazing talent that they’d already developed. “I always try to have themes that are enjoyable, and will leave the audience members inspired,” says concertmaster Yuriy Bekker. “These artists were child prodigies, but these incredible pieces are rarely performed.” Mozart had changed music forever by the time he died at 35, and Mendelssohn had made his own prolific contributions to music when his life ended at age 38. Though Mozart usually hogs all the attention (Amadeus, anyone?), the star of this show is Mendelssohn, who is better known for his more conservative, later works than his risk-taking ones. As a result, fans may be surprised by what they hear — the CSO will be performing the Sinfonia No. 11, one of Mendelssohn’s most innovative and out-of-the-box pieces.
