TriMusica, consisting of clarinetist Sandra MacPherson, cellist Susan Lamb Cook and pianist John Cozza, started playing together in 2015 and since then have performed in over 25 concerts together. Their repertoire consists not only of the standard works for their ensemble (Beethoven and Brahms Clarinet Trios), but also arrangements (Mozart Kegelstatt Trio, Bruch Pieces Op. 83, Schumann Fantasiestücke Op. 74) and contemporary works (Rota Trio, Hsieh Elegy for a Sphere, delAguila Tango Trio). TriMusica has also premiered several works commissioned by local composers (Stephen Blumberg Aura in 2016 and Jeffrey Hoover Oneness in 2019).
