Jill Sigman/thinkdance improvisation
Jan 31st
This time last week I had the pleasure of working with choreographer Jill Sigman/thinkdance and videographer Peter Shapiro who were artists-in-residence at EMPAC. I recorded some sounds of the objects and materials Jill was working with and then improvised with the samples, my fretless banjo, and vocalist/composer Kristin Norderval (remotely via Skype). Peter has posted some raw footage from our sessions.
I look forward to seeing how this project continues to take shape.

Hemi Speaker and Our Lady of Detritus
Sep 14th
I recently had the opportunity to help Kristin Norderval build a hemispherical speaker for use in the jill sigman/thinkdance production, Our Lady of Detritus, engagingly described as “a portable, interdisciplinary performance installation about trash and transcendence; a traveling grassroots campaign fueled by experimentation, green energy sources and community interaction.” The show is presented every weekend through mid-October at various locations around New York City. See here for details.
The speaker was based on the Princeton Laptop Orchestra (PLOrk) Delorean speaker and the Stanford Laptop Orchestra (SLOrk) speakers.
Enclosure
We used an Ikea salad bowl for the enclosure just like the SLOrk speakers.
Amps
We pulled 3 Dayton T-amps from their enclosures and mounted them on the inside of the bottom plate of the speaker cabinet.
Speakers
We used 6 4″ Inifinity 4022i drivers.
Volume Pots and Connectors
The Dayton amps had combination volume and power pots, so we decided to keep them rather than source and wire up a 6-position potentiometer. A little Dremel routing magic made mounting the volume pots easier than I expected. A coaxial power jack and 6-pin Neutrik XLR jack and plug rounded out the connectors.

The speaker sounds good–punchy and more powerful than I expected, particularly considering the 4″ drivers. I’ll be building one for myself soon.
