May 15: HOME RADIATION at Defibrillator


Defibrillator is proud to present




Performing with radiophonic instruments, unique homemade electronics, micro-watt transmitters, and re-purposed objects, ANNA FRIZ, JEFF KOLAR and ERIC LEONARDSON create intimate atmospheres traversing acoustic and electro-magnetic space. Together their work can be characterized as a mindful collaboration with vibrational surfaces and unstable circuits; and with subtle treatments of potentially noisy, often lo-fi materials from which highly detailed landscapes emerge. Though all three artists have worked with one another in various constellations in Chicago and internationally, this concert is their premiere outing as a trio.

The Arcade | Chicago Curates Columbia: Audio Arts and Acoustics

I recently helped students in Jesse Seay’s Sound Art Electronics class use piezo disc contact microphones to build amplified sound sculptures and instruments for public interaction at The Arcade, an exhibition space at Columbia College Chicago. Their handmade electroacoustic creations were very fun and effective. The show runs for one month and closes May 2, 2014.

In addition to piezo disc contact microphones, Jesse’s students made many simple light-sensitive oscillators grouped together in a wonderful installation room within the gallery, and in one playful—and soundful—sculptural object.

Tortua video online

Published on March 26, 2013

Tortua is a robotic video artwork that was on display in the Eli Marsh Gallery at Amherst College, on March 4–27, 2013. The installation incorporates a digitally animated sequence by Rebekah Tolley, a robotic sculpture by Micheal Tolley and audio by Eric Leonardson.

Sound and Image at Eli Marsh Gallery – Opening Monday, March 4

rebekah tolley - tortuaI made new sounds to accompany two of Rebekah Tolley’s animated image sequence projections of organic life forms. One of these sounds is part of a robotic piece. These are among her visual works on display at the Eli Marsh Gallery next week, Monday, March 4, 2013 at Amherst College.

rebekah tolley - spiderAt 4:30 on Thursday, March 7 Rebekah Tolley gives a lecture on her work at Pruyne Lecture Hall, 115 Fayerweather. A reception follows at the Eli Marsh Gallery.

Rebekah Tolley is a printmaker, digital media artist. Visiting Artist-In-Residence in the Department of Art and Art History at Amherst College where I am in residence, as a Copeland Fellow.

My sounds accompany two video installations. One is titled, “Molting.” This slowly changing, animated image sequence is projected a white handmade paper sculptural form on the gallery floor. “Tortua” is the title of the other installation. Its image sequence is projected onto a robotically inflated pneumatic sculpture. The images in both pieces come from ocean life forms, specifically a molting crab and a seashell. My sounds are recorded were made using analog synthesis, and digital post processing of the audio’s spectral content, to create slowly changing swells that ebb and return. We hear a single sound that hovering in a stationary place, that always changes internally, similar in character to the pace of changing shape and colors in the images.

This video shows “Tortua,” with robotics by Mike Tolley, followed by “Molting.” Mike and I will will talk a about our contributions at Rebekah’s lecture this Thursday, March 7 at 4:30 pm in Pruyne Lecture Hall and Eli Marsh Gallery, 115 & 105 Fayerweather Hall, Amherst College.
