Cordis Quartet has been redefining contemporary chamber music by fusing an original combination of custom-made and traditional ethnic instruments to create their signature sound. This chamber rock group of Boston based musicians bring that sound, and their unique array of instruments, to the historic Opera House stage on Saturday, July 13 at 7:30 p.m.

The program will include both their own compositions as well as the “Metamorphosis Suite” by Phillip Glass and the “Symphony of Psalms” by Igor Stravinsky.

Although the ensemble is built upon cello, performed by Jeremy Harman, concert cimbalom, played by Richard Grimes, piano played by Brian O’Neill and percussion performed by Andrew Beall – one-of-a-kind creations such as the electric mbira, melodic and the world’s longest playing cylinder-driven music box also have a way of weaving their way into any given performance.

Tickets purchased in advance are discounted and are available for $16. Tickets purchased on the day or night of the concert are $21. Doors for seating open at 7:30 p.m., with the concert beginning at 8 p.m.

The Opera House box office is open Tuesday through Friday from 10 a.m. to 4 p.m. at 86 Townsend Avenue in Boothbay Harbor, or by calling 633-5159. Tickets are also available online at boothbayoperahouse.com.
