Now in its 38th year of performance, the charming "Symphony on the Bay" exudes a passion for music and community, offering a bevy of concerts to please young, old, and canine listeners alike. "Celebrating Fifteen" honors James R. McKay's 15 years as Symphony Hamilton's music director. In addition to conducting the community-based volunteer symphonic orchestra, the maestro stays active as a bassoonist, acoustic researcher, and university teacher. "A Family Christmas" will offer a slew of traditional Christmas songs featuring mezzo-soprano Sophie Roland and a mandatory Christmas-carol sing-along. "Beethoven's Heroines and Emperors" will contain classics such as the Leonore Overture No. 3 and Symphony No. 3, "Eroica." "Film and Symphonic Classics" will feature pieces by Mozart, Barber, and Dvorak, as well as John Williams' Schindler's List and The Imperial March from Star Wars Suite. Guest conductor Pratik Gandhi will lead "Music Through the Ages" with numbers from Holst, Mozart, and J.C. Bach.
