Historical keyboard specialist Sylvia Berry and the Berry Collective, an ensemble of some of today’s best early-music players, are joined by violinist Marika Holmqvist and cellist Katie Rietman, who’ve both performed throughout Europe and the U.S., for Crowd of Three, a program of piano trios including J.C. Bach’s lovely Op. XV, No. 2 in A major, Haydn’s passionate trio in G minor, Hob. XV: 1, and Mozart’s ebullient trio in C major, K. 548. Gore Place welcomes Crowd of Three to Boston.
