Bay Chamber Concerts opens its summer series at Rockport Opera House with the Jupiter Quartet in a program titled “Imprimatur” on Thursday, July 11, at 7:30 p.m. Cellist Jeffrey Zeigler will join the quartet for Friday’s concert, “The Sounds of Science,” on Friday, July 12, at Union Hall in Rockport at 5:30 p.m. And, at 8:30, Zeigler and the Jupiter Quartet will present “A Cyclic Expedition.”

The performance on Thursday includes Mozart’s String Quartet in A Major, K. 464; Dvorák’s String Quartet No. 13 in G Major, Op.106; and Kati Agócs’ “Imprimatur” (2018). “Imprimatur” was commissioned to celebrate Jupiter’s 15th anniversary.

Friday’s 5:30 concert will feature new music written for amplified cello and electronics by several composers. Jeffrey Zeigler, longtime member of Kronos Quartet, co-curated the program with composer-bandleader Graham Reynolds. Paired with scientists of their choosing, composers created music inspired by and reflective of the scientist’s life and practice.

“A Cyclic Expedition,” at 8:30, will include Boccherini’s Cello Quintet in C Major, Op. 30, No. 6; Shostakovich’s String Quartet No. 11 in F minor, Op. 122; and Mendelssohn’s String Quartet in A minor, Op. 13.
