PCMS celebrates Maurice Ravel’s 150th birthday with two programs (the second on May 6) dedicated to this extraordinary French composer, pianist, and conductor. The first event features “supremely musical” (The Strad) violinist Hye-Jin Kim and fellow Society favorites cellist Peter Stumpf and pianist Cynthia Raim in a program culminating with the composer’s Piano Trio in A Minor. This trio is acclaimed for its fresh and compelling musical voice, and for uniting an immediate sensual appeal with a brilliantly-crafted architecture.
