In the history of the Marin Symphony, violinist and concertmaster Jeremy Constant has been one of the most admired members of the company. This year, Constant marks two decades with the symphony, and this week he is featured as the violin soloist for Marin Symphony’s third Masterworks concert, ‘Eight Seasons.’ Performing Vivaldi’s The Four Seasons with tango master Astor Piazzolla’s The Four Seasons of Buenos Aires, Constant delves into both the complex differences and similarities between the works in an interweaving musical program of juxtapositions and surprises. Constant’s talent and wit are on display when he and the Marin Symphony perform “Eight Seasons” on Sunday, Feb. 15, and Tuesday, Feb. 17, at Marin Center’s Veterans Memorial Auditorium, 10 Avenue of the Flags, San Rafael. Sunday at 3pm; Tuesday at 7:30pm. $15–$20. 415.473.6800.
