Music Director David Lockington recently opened the Pasadena Symphony’s 91st season with Mendelssohn’s String Symphony No. 3 at the Ambassador Auditorium. Also on the program was Elgar’s Introduction and Allegro and the title piece for the evening, Mozart’s hauntingly beautiful Requiem. Guests enjoyed pre-concert libations and a custom fall menu by Claud & Co. in the Symphony Lounge.
