Years after writing his perennially popular Second and Third Piano Concertos, Rachmaninov fled the turmoil of the Russian Revolution and settled in New York. His Piano Concerto No. 4, composed largely in this new American milieu, is animated by jazzy undertones and bold chromaticism almost suggestive of Gershwin, but we still hear the aching nostalgia that characterizes much of Rachmaninov’s work. De la Salle navigates virtuosic passages with astonishing ease and expertly evokes the great Russian's romantic pathos.

In honor of the 150th anniversary of Nielsen’s birth, the concert features his final masterpiece Commotio (1931), written in the style of a Baroque toccata with alternating fantasy and fugue sections. His enigmatic Sixth Symphony, dubbed the Sinfonia semplice (Simple Symphony—a misnomer, to be sure), caps the evening, demonstrating the Dane’s adventurous spirit with shifting tonality, an unconventional structure, and a winning blend of humor and profundity.
