The Mahler Chamber Orchestra returns with pianist Mitsuko Uchida, continuing a multiyear collaboration to bring Mozart’s piano concertos to Berkeley audiences. These original compositions are a boundless playground where Mozart explored new ideas of musical drama, form, and ensemble interplay. A revered Mozartean, Uchida has lived with these works for decades, performing and recording them to great acclaim, and she has spoken about the merits and pleasures of returning to familiar repertoire throughout her career. The composer’s music, she has said, “is about conversation and happiness and joy and sorrow and life. Mozart wrote so many wonderful pieces, but for me his concerti are infinitely deeper and varied, and each is an instrumental opera.”
