HARRISON  —  The third concert of the Sebago-Long Lake Music Festival’s 45th anniversary season continues at the Deertrees Theatre at 7:30 p.m., Tuesday, July 25, with a dynamic Russian program, “A Postcard from Russia.” The Russian spirit is alive and well in the music of four composers who lived in different eras and composed under dramatically different circumstances. This concert is also a celebration of life as the festival dedicates the program to its founding member, the late Paul Boyer, flutist, and to long-time violinist, the late Paul Wolfe.

This season extends through August 8.

Tuesday’s program: Prokofiev, Melodies for Violin and Piano, Op. 35b; Gliere, Suite for Violin and Bass, Op. 39; Shostakovich, Piano Quintet in G Minor, Op. 57 and Tchaikovsky, Sextet for Strings, Op. 70, “Souvenir de Florence.”

Performers: Mihae Lee, music director and pianist; Varty Manouelian, violinist of the Los Angeles Philharmonic; Movses Pogossian, professor of violin at the UCLA Herb Alpert School of Music; Tien-Hsin Cindy Wu, award-winning violist and violist; Laurie Kennedy, principal violist of the Portland Symphony; Elizabeth Anderson, cellist of the Cassatt String Quartet; Bonnie Thron, principal cellist of the North Carolina Symphony; Anthony D’Amico, principal bass of the Boston Modern Orchestra Project and the Boston Philharmonic.
