If the 200-plus guests at the April 9 Princeton Symphony Orchestra gala didn’t arrive with rhythm, they got some soon enough at the sold out event at Jasna Polana. The theme was Gersh­win in Paris, and the revelers were treated to the sights and sounds of jazz-age Paris. Patrons sipped cocktails and ate canapes prior to being called to dinner by a brass fanfare by PSO musicians.

Music director Rossen Milanov welcomed everyone and conducted George Gershwin’s “I Got Rhythm” as flappers from the American Repertory Ballet performed a jazz challenge dance choreographed by Mary Pat Robertson. More dancing was encouraged with the vintage jazz and classic swing sound of Lapis Luna.

Co-chairs Beth Beers and Nora Decker included a performance by PSO musicians at the event. “It’s a really nice marriage between what we’re raising money for and being able to experience a great performance,” Decker said. Funding from sponsors, individual donations, and the gala’s live auction significantly exceeded last year’s proceeds, making it the most successful gala ever.

A new element: The Fund-A-Need: PSO BRAVO! Challenge, to support the program that reaches 10,000 students every year, providing free performances, coaching, music instruction, and opportunities for creative engagement.
