Most artists don’t record in canyons.

But Andrew Bird did, and it can be heard being played through over 30 colorful, Dr. Seuss-like speakers at the Institute of Contemporary Art. The exhibition, Sonic Arboretum, on which he collaborated with sculptor and instrument-maker Ian Schneller, opened Wednesday.

Bird, a primarily indie-folk musician, recorded himself playing the violin, along with the occasional whistling and sound of flowing water in the Coyote Gulch canyons of Utah.

Deviating from Bird’s usual singer-songwriter material, the recording is a 50-minute-long nonstop experience. If you had to slap a genre label or two on “Echolocations: Canyon,” as it’s called, you would have to call it avant-garde. It’s melodious, but the bouncing, reverberate echo effect of the exhibition makes it just as much about stylized ambiance as it is about composition.

But one genre doesn’t quite do it justice. The piece often breaks into segments that feel more like the score to a Hayao Miyazaki film than anything else. (I’d like to quickly take a step back from this piece to formally request a Miyazaki-Bird collaboration.) The oscillation between the feels of scientific exploration of echoes and the visceral, driving nature of the arrangement gives the piece a depth worth talking about.

Schneller’s role in the exhibition is not to be shoved aside, however. He was the one to meticulously place each of the 30-plus speakers made from recycled newsprint, dryer lint, baking soda and more on all four sides of the museum room.

The smaller details too, make what he accomplished technically impressive. To get all of the speakers to play the track at the same exact time, a multitude of iPod nanos have to be synchronized at a level of precision that is beyond human capability. To work around this, Schneller took the route that only a sculptor-instrument-maker would take: he created a device that hits play on up to ten iPods at a time, at the exact same moment. It’s called the Nano Sync, and it wouldn’t be art if it wasn’t as colorful and visually stunning as the rest of the audio equipment in the room, would it?

All together, the sonic and visual components come together to form a surreal experience. Whatever you’re thinking about when you walk into the exhibition, your mind will probably entirely lose sight of it in the process of calibration.

How much you get out of Sonic Arboretum also depends on how much time and attention you give it. Because there’s more art outside both entrances to the room, it’s easy to walk in, listen for a minute or two, and then continue on with your museum tour. There’s nothing necessarily wrong with that approach. You have enough time to appreciate the visual aesthetic of Schneller’s artful speakers and get a general sense of Bird’s music, even if it’s on a relatively superficial level of understanding.

But if you want to stop, sit down on the bench in the center of the room and close your eyes, you can do that too. (And you won’t be alone, chances are). You can try to picture yourself sitting down cross-legged in a solitary canyon in Utah while a renowned musician plays his violin not too far away, if you’d like. Or you can let your mind wander and let Bird’s music be a backdrop to your thoughts.

As is the nature of modern art, there is no one expected outcome, as cliché as it sounds. There’s no specific way you’re supposed to think or feel when you walk out. It’s considerably liberating in a sense.

The installation, Sonic Arboretum, has been around since 2010, but it previously featured Bird performing live through the sound system. The pre-recorded “Echolocations: Canyon,” is the first of its kind in an “Echolocations” series. To follow in the upcoming years are “River,” “City,” “Lake” and “Forest.”

You can guess where he will record each one, but not where each one will take you when you hear it.

Sonic Arboretum is on display at the Institute of Contemporary Art through May 10.

I will present brand new Sculpture/Sonics: Aero Dynamisms April 11- May 31 at the Packer Schopf Gallery in Chicago.


One system will present music through a choreographed duet of spinning horns (creating an acoustic phase shifting/Doppler effect ) and two rafts of static horn speakers connected to 10 channels of single-ended tube amplified audio from iPod Nanos via my nano-sync apparatus.

Another system, is comprised of 8 beautiful, never before seen individual horn shapes powered by a single ended 8 channel triode powered electron tube Octoblock amplifier.

The music is mixed to 8 channels – and emanates from the 8 horn shapes, each representing different members of a chamber orchestra. This system presents a new type of compositional tool via a Mac Book Air.

Sound content for both systems will be new compositions by Glenn Kotche with performances by eighth blackbird and Kronos Quartet – pre-recorded as digital data on iPod Nanos and separate compositions on the laptop system.


This installation will create a spatial sonic atmosphere imbued with a phantom chamber orchestra playing music through sculpture.

The digital technology feeds directly into 1940’s eratube technology/topology, marrying the past to the present.

The stunning contrast between the two technologies represents time travel and creates quite a beautiful sensation through a brand new type of aural presentation that can only be experienced on location.

The show runs through May 31 and I dare say, that a visit apart from the opening for a more private experience should provide an astonishing and playfully surreal experience.


Aero Dynamisms opens Friday  April 11  5-8 pm.

Please join us for the opening reception of Ian Schneller’s newest sound installation:


Elgin Arts Center
September 24, 2013
5:00 – 7:30 pm

This exhibit will include a unique sound installation of horn speakers, tube amplifiers, and spinning Aerosel sculptures. The horn speakers are powered by tube amplifiers that are connected to ten Apple iPod Nanos containing the entire musical score Andrew Bird composed exclusively for the Sonic Arboretum. This co-mingling of 1940s tube technology with modern digital components creates an aural and visual installation that can only be experienced on location. The exhibit will be controlled by Ian’s newest creation, the Nano-Sync Apparatus, which when activated will simultaneously start all 10 iPod Nanos. Ian and his team will be demonstrating the Nano-Sync Apparatus at the opening reception.

For those of you who missed the 2011 Sonic Arboretum exhibition at the Museum of Contemporary Art in Chicago, this is a rare opportunity to see Ian’s special sonic installation and to hear compositions by Andrew Bird that are unavailable anywhere else.

The exhibit runs September 24 – October 29, 2013 at Elgin Community College Art Center in Elgin, Illinois.

This new combo amp in the works is for amplifying stringed instruments. The cabinet follows the construction details of both the Specimen Tube Amps and Horn Speaker bases. It also uses the engine turned sub-plates for convection cooling found on Specimen’s Octoblock and the slotted side panels that were first used on Specimen’s Fifty-watt Tube Amp. You could say it’s a clever combination of several Specimen innovations all rolled into one beautiful package.

This project stemmed from a request to revisit the original Horn Amp Combo I made about fifteen years ago. This model will use the splendid Eminence 8-inch guitar speaker rear-loaded with a vertical horn. The obvious follow up to this project will be a symmetrical pair of hi-fi mono blocks with a 6 1/2″ Fostex speaker.

All that’s left to do is apply the finish to the amp and horn, wire up the amp and machine the back panel. More pics soon!

Since the Gimbal Horns are going to be hanging from the ceiling, utmost care is required for the design of the support mechanisms. Its mounting hardware is machined from aluminum rod stock. Simple details like this contribute to the structural fortitude of the final product.

In order for the mounting hardware to be flush fit to the cylinder, I created a special fixture that cuts the matching radius of the cylindrical compression chamber, ensuring a perfect fit. An indexing plate is attached to one side of the cylinder so that a hardened steel pin can fit through a press-fit bushing in the yoke and determine the horizontal orientation of the horn. Holes are transferred from a template and drilled into their respective parts.

Below is a slideshow of photos taken during the building process. Check our my other Blog posts for more information and photos about this newest Specimen.
