Jun Märkl’s second consecutive week with the NSO offers a program consisting of the standard formula of overture-concerto-symphony. But there is nothing ordinary about any of the three compositions on this program. Berlioz’ overture portrays the exhilarating joy of Carnival season in music of great orchestral brilliance and rhythmic energy. Walton’s Violin Concerto is one of the finest of its genre from the twentieth century, music of sensuous lyricism, a tonal orientation spiked with dissonance, hard-edged brilliance, and rhythmic virility sometimes tinged with jazz. Like all great composers, Walton has an immediately identifiable quality to his music that marks it unmistakably and exclusively his own. He wrote his Violin Concerto for Jascha Heifetz, who gave the world premiere in 1939. The NSO’s soloist is Taiwanese-born Paul Huang, recipient of innumerable prestigious awards over the past ten years. Brahms’s magisterial Fourth Symphony, which concludes Slatkin’s program, is filled with wonderful moments that arrest the attention, and has been described as “tragedy with unsurpassable variety of expression and power of climax.”
