True to the spirit and practices of Music@Menlo, a galaxy of musicians have come together to create an extraordinary substitution program for this Sunday’s Carte Blanche program. Although violinist Kristin Lee is under the weather, her collaborator, pianist Michael Stephen Brown, is participating in a full program of works for piano, and pianos, which now involves the entire Music@Menlo piano on-site piano roster, including Wu Han, Gilbert Kalish, and Hyeyeon Park. The concert opens with one of the most iconic works in the four-hand piano literature, the effervescent, jubilant Sonata in C major by Wolfgang Amadeus Mozart. True to the French Reflections festival theme, the Mozart is followed by an entertaining duo sonata by one of the most prolific and popular French composers of the 20th century, Francis Poulenc. The first half concludes in a blaze of virtuosity from the child prodigy Felix Mendelssohn, whose technique knew no limits. His Allegro Brillant for piano, four hands, is one of the most popular works in the duo piano literature. After intermission, Michael Stephen Brown offers Music@Menlo an extraordinary opportunity: to witness the world premiere of a new work just composed at the Yaddo artist retreat. Michael will speak of the extraordinary genesis of this work from the stage. Once again reflecting France, Claude Debussy’s Petite Suite is followed by George Gershwin’s Rhapsody in Blue, a work which changed the landscape of both jazz and classical music since its premiere in New York’s Aeolian Hall, by the Paul Whiteman Band with the composer at the piano. Such a pivotal musical occasion attracted a packed house which included violinist Jascha Heifetz, pianist Sergei Rachmaninov, bandleader John Philip Sousa, and conductor Leopold Stokowsky. Come celebrate this historic work’s 100th anniversary with Music@Menlo.
