Despite the distant threat of rain – “the necessary shadow,” as the composer called it – Brahms’ Second Symphony is a sunny and idyllic work beloved for its rambunctious joy and its balance with that hint of cloud. Eun Sun Kim, a conductor of “assured technical command, subtlety and imagination” (New York Times), leads this program, which opens memorably with the “electro-acoustic soundworld” of Mason Bates’ Rhapsody of Steve Jobs. Gramophone calls Johannes Moser “one of the finest among the astonishing gallery of young virtuoso cellists,” and there is no finer showcase of Moser’s musical prowess than Shostakovich’s boisterous and demanding First Cello Concerto.
