On the Concord and Merrimack

concept and execution: Tim Wojcik
programming: Guy Dupont

An interactive installation inspired by the travels of Henry David and John Thoreau.

16mm film, perchloric acid, brain waves, cotton, and 5.1 sound, 2018

As you chart the course that Thoreau traveled in 1839,
allow pollutants of mind to adjust your view. 

Submerged in sounds of the river,
you see degrees of distress—
caused by chemical pollution 
and determined by the activity of your mind. 

from Concord, MA to Concord, NH, 16 minutes


captured with brain wave activity provided by the artist

recorded as installed at Emerson Urban Arts Gallery on May 9, 2018

gallery instructions

On the Concord and Merrimack
an interactive multimedia experience for one

You are invited to listen without association, 
to see without attachment, to breathe, and to be.

To experience the work as intended, you are asked to wear a brain-wave reading headband.
This commercially-manufactured device (muse by Interaxon) reads your brain activity in
alpha, beta, delta, gamma, and theta waves.

In this piece, alpha wave activity is employed to visually recall the river’s pollutants.
