Interface is committed to free-improvisation and electronic music composition.
The duo has performed throughout the Northeast and abroad, recently appearing at the International Computer Music Festival in Greece. Trueman plays a custom six-string electric violin and the Norwegian Hardanger fiddle. He uses a special spherical speaker called the Bomb and a device called an R bow, an electric bow fitted with some sensors that can detect motion and pressure, for his violin. He is also involved with a project called N-Body, which involves the directional tonal radiative qualities of various acoustic instruments. Trueman studied physics at Carleton College and composition at the College-Conservatory of Music in Cincinnati.
