Selected discography


Shawn Greenlee is a composer, sound artist, and Professor at Rhode Island School of Design (RISD) where he leads the Studio for Research in Sound & Technology (SRST).  His recent work explores spatial audio, high density loudspeaker arrays, and erratic sound synthesis techniques.

Greenlee has been active as a solo electronic / electroacoustic improvisor since 1997 and has toured extensively across the US and Europe. Conference and festival performances include New Interfaces for Musical Expression (2018 Blacksburg, 2015 Baton Rouge, 2014 London, 2013 Daejeon), International Computer Music Conference (2021 Santiago, 2018 Daegu, 2011 Huddersfield, 2005 Barcelona), BEAST FEaST (2017 Birmingham), PdCon16 (2016 New York), Cube Fest (2019, 2016 Blacksburg), Re-new (2013 Copenhagen), IN TRANSIT (2008 Berlin), and Elevate (2007 Graz), among others.

Greenlee’s solo and group discography spans over fifty releases. Greenlee is a founding member of Landed, active since 1997 and known for its deconstructed rock, rhythmic noise, and intense live performances. From 1999-2001, he performed with Six Finger Satellite.

Greenlee holds a Ph.D. in Computer Music and New Media from Brown University

Adder (2012-13)

Adder is a system for synthesizing sound from visual image data, scanned during composition/performance. Adder relies on an additive synthesis procedure where color values are extracted from pixel rows and used to set the volumes and spatial locations for banks of harmonic oscillators each tuned to a specific pitch. Red and blue values correspond to left-right panning, while green values center the sound in the stereo field. With the screen interface, magenta and orange line-graphs each display one channel of spatial activity (left and right in the stereo field), with the height of the line corresponding to the pixel’s influence on the amplitude of the available oscillators. At the bottom of the display is a white graph that shows the tuning for each oscillator overlaid with a real-time spectral analysis of the audio output. While many timbres are possible, the selected character for the sound of Adder is organ-like. 

Adder was used to create Iapetus Trace, which utilizes prepared photographs of Saturn’s moon Iapetus, taken by the NASA spacecraft Cassini. The graphic score shows the moon’s topography remapped with color gradients that enable the surface illumination to become audible through panning cues (sonifying topography). Iapetus Trace was on listen at the Deep Space exhibition in July-August 2012 at François Ghebaly Gallery in Los Angeles. Further, Adder has been used in live performance contexts and for talks on Graphic Sound.
