Opus Two
  Biography

William Terwilliger, Violin
Andrew Cooperstock, Piano
 
The award-winning Opus Two has been internationally recognized for its “divine phrases, impelling rhythm, elastic ensemble and stunning sounds,” as well as its commitment to expanding the violin-piano duo repertoire. Seasoned chamber players, violinist William Terwilliger and pianist Andrew Cooperstock specialize in the duo literature and have developed an uncanny sense of musical unity.

Winners of the United States Information Agency’s Artistic Ambassador Auditions in 1993, Opus Two embarked on a 30-concert tour of Latin America and the Caribbean, which included performances, radio broadcasts and master classes throughout Chile, Peru, Ecuador, Bolivia, Panama, the Dominican Republic and the Bahamas. The overwhelming success of that tour launched the duo on a distinguished concert career on four continents. Further international engagements have included performances in France, Belgium, Holland, England, Scotland, Sweden, Germany, Latvia, Ukraine, Canada and Australia. Opus Two has concertized across the United States, including recitals in New York, Chicago, New Orleans, Detroit, Houston, Dallas, Denver, Minneapolis and Baltimore.
 
In April 2006, Opus Two made its Asian debut, with recitals, concerto appearances and master classes throughout China, Korea, Japan and the Russian Far East, in such locales as Beijing, Tianjin, Nanning, Shenzhen, Seoul, Sapporo, Okinawa, Kobe, Kanazawa, Khabarovsk and Vladivostok, among others. Highlights of recent seasons include the ensemble’s debut at London’s St. John’s, Smith Square, following which The Strad remarked that “violinist William Terwilliger played with supreme tenderness and finely judged control and was partnered with assurance and sensitivity by Andrew Cooperstock.” Opus Two’s recent festival appearances include performances at the Australian Festival of Chamber Music (Queensland), Piccolo Spoleto (South Carolina), the Round Top International Festival-Institute (Texas), and Brevard Music Festival (North Carolina).

Champions of American music, Opus Two has performed Aaron Copland’s complete works for violin and piano extensively across the United States and abroad. The duo’s recording of this same music (Azica Records) features works never before recorded, including two early, unpublished preludes. Of this recording American Record Guide remarks that “it would be hard to imagine finer performances of these works.” Leading Aaron Copland biographer Howard Pollack applauds the duo’s “utterly compelling performances of Copland’s music for violin and piano, full of tenderness and sensitivity in slower passages and vigor and buoyancy in faster ones.” The ensemble’s most recent recording, Chamber Music of Lowell Liebermann, features performances with cellist Andres Diaz and the Ying Quartet, and was praised as “splendid” by Strings magazine. Earlier this year, the two won a grant from the American Music Center’s Aaron Copland Recording Fund, which will be used to release Souvenirs: Music of Paul Schoenfield in the 2006/07 season. Opus Two’s discography also includes two discs of works of Robert Starer, one of which features the world premiere recording of Dispositions with clarinetist Martha MacDonald, a work that was composed especially for them.
 
In addition to their concerts as Opus Two, William Terwilliger and Andrew Cooperstock frequently join forces with Martha MacDonald as members of Trio Contraste. The Trio has been honored with the Centennial Chamber Music Award for Outstanding Promotion of American Music from the National Federation of Music Clubs.
