Evidence is a collaboration between sound artists Stephan Moore and Scott Smallwood, with activities ranging from studio compositions and live improvisations to sound installations, street performances, and numerous collaborations with other musicians, choreographers, and video artists. Since 2001, they have developed a distinctive language of deeply layered sound, using field recordings of natural and industrial sounds as a primary source of inspiration and sonic material. Recent projects include the participatory performance/installation "Receiver", which broadcasts multi-channel compositions on several closely-tuned FM frequencies to a radio-wielding audience, and "Losperus", a performance of unstable sound sculptures, fashioned improvisationally from discarded household items.

Stephan Moore is a composer, audio artist, and sound designer from Marquette, Michigan. His creative work centers around the collection of real-world sound, the creation and perception of sonic environments, and technological manifestations of improvisation and interactivity. Recent performances and installation artworks make use of his Hemisphere speakers. He collaborates regularly with Scott Smallwood in the electronic duo Evidence, and with a variety of musicians, live-video artists, and choreographers. He is currently the Sound Engineer and Music Coordinator of the Merce Cunningham Dance Company.

Scott Smallwood was born in Dallas, Texas, and grew up at 10,000 feet in elevation in the Colorado Rockies. When Smallwood was 10 years old, his father gave him a cassette tape recorder, and ever since he has been fascinated by the possibilities of recorded sound. His work deals with real and abstracted soundscapes based on a practice of listening, improvisation, and phonography. Ranging from sonic photographs, studio compositions, instrumental pieces, and improvisations, the resulting pieces are often textural, always mindful of space and subtlety.

Stephan Moore lives and works in Brooklyn, New York, United States. Scott Smallwood lives and works in Edmonton, Alberta, Canada.
