With several performances per year since 1990, Musical Masterworks has managed to bring impressive world-class talent to Old Lyme, each time putting on a performance for the ages.

December’s show promises to deliver again, with internationally acclaimed violinist James Ehnes, one of the foremost violinists of his generation (he is 41), and his Ehnes Quartet making their Masterworks debut Saturday and Sunday in Old Lyme.

Besides Ehnes, the quartet is comprised of internationally renowned string musicians: violinist Amy Schwartz Moretti, violist Richard O’Neill, and Musical Masterwork’s own artistic director and cellist, Edward Arron. The group, together since 2010, has played across North America, Europe, and Asia and is one of the most sought-after chamber groups today.

In a performance featuring their refined, sensitive and expressive style, the group will play Haydn’s String Quartet in G Major, Opus 76, No. 1; Bartók’s String Quartet No. 2, Sz. 67; and Beethoven’s String Quartet in C Major, Opus 59, No. 3.

Another note: don’t miss out on a pre-concert talk, held before both performances. Hosted by Arron, the presentation will feature an in-depth discussion about the composers and music featured over the weekend.
