Conductor Kevin John Edusei leads a program that invites you to explore the concept of harmony and its many forms, beginning with Elysium by Samy Moussa, a composer who has a “gleeful sense for…shocking harmony” (Los Angeles Times). John Adams describes his rhythmically and harmonically complex Harmonielehre as a parody “without the intent to ridicule,” with “shades of Mahler, Sibelius and Debussy.” Both pieces frame George Li’s performance of the Second Piano Concerto from Rachmaninoff, arguably the hero of the lush, romantic style.
