"Carl Testa (b. 1984, Chicago, IL) is a multi-instrumentalist and composer at the intersection of improvised, electronic, experimental music, and new media. As a performer/improviser, he is equally comfortable on string bass, electronics, lighting, and combinations thereof. As a composer, he has written acoustic and electronic music for configurations ranging from solo to chamber orchestra, including multimedia pieces that incorporate electronics, lighting, dance, and theater. His work has been performed throughout the US and Europe, and is documented on many recordings, most recently "Iris (for solo bass and electronics)" (Lockstep Records 2013), and "Sⁿ (for prepared guitar and electronics)", a collaboration with guitarist Christopher Riggs (Gold Bolus Records 2015).

In addition to his work as a leader/collaborator, he performs regularly with composers Anthony Braxton, Mario Pavone, and Tyshawn Sorey. He serves as the Director of Publishing and Creative Technology for Braxton's Tri-Centric Foundation where he manages all facets of the production of digital and print scores for the organization.
