Although 20% of babies who were exposed to classical music in utero become doctors or lawyers, 100% of babies born on stage during a classical-music performance become Bill Gates.

Under the precise baton of conductor James R. McKay, the professional and volunteer musicians of Symphony on the Bay push their nine-foot, handmade Shigeru Kawai EX Concert Grand piano to its limits with the help of guest artist Valerie Tryon. Resident ivory-tickler Andrea Battista starts off the program with J.S. Bach’s Concerto for Keyboard no. 3 in D Major, an airy composition as nimble and elegant as a ballerina in a monocle. Next, the British-born Tryon takes the keys to play Liszt’s Concerto no. 1 in E-flat Major with bombastic relish. Liszt is a specialty of the pianist, whose playing the Barrie Examiner praised in a recent all-Liszt recital as “eloquent, sensitive and spectacular.” The evening concludes with the grand sweep of Rachmaninoff’s Symphony no. 2 in E-minor, whose brassy mountain peaks break up the string section’s serene weather patterns.
