Krzysztof Meyer Imaginary Variations, Op. 114 San Francisco Premiere; written for Janet PackerVittorio Rieti Rondo Variato in F majorClaude Debussy Sonata in G majorGabriel PiernÃ© Sonata in D major, Op. 36Janet Packer, a violinist with â€œan opulent tone, a swashbuckling bow arm, meticulous intonation, and a keen sense of gestureâ€ and Geoffrey Burleson, â€œa remarkable pianist, with tireless attack, unflagging rhythm and energy to burn,â€ travel from Boston and New York City to bring to Old First Concerts a San Francisco premiere by one of Europes most distinguished living composers. Krzysztof Meyer (born in Poland in 1943) wrote the deeply expressive and powerfully moving Imaginary Variations for Violin and Piano for Janet Packer in 2010. Composed 62 years earlier, the witty and elegant six-minute Rondo Variato of Vittorio Rieti was the composers favorite of his violin-and-piano compositions. Claude Debussys beloved Sonata for Violin and Piano provides an exhilarating conclusion to the first half of the program. Gabriel PiernÃ©s marvelous and rarely heard Sonata for Piano and Violin, completed just days before the close of the 19th century, is passionate music which yet evokes a French suavity both earnest and appealing. The second movement, not truly a slow movement, has the innocent charm of a folk melody, while the outer movements abound in rhythmic energy and Ã©lan.
