Experimental Music Mondays: Ephemeral Structures

Posted on April 26, 2010 by John C.S. Keston

This Monday, April 26, 2010 is the third installment of Experimental Music Mondays at the Kitty Cat Klub in Minneapolis, Minnesota. The line-up includes violin soloist Kip Jones, Ephemeral Structures, and Primidonahue (Michael Donahue). The music will start at around 9:00pm and there’s no cover to get into the club.

Yesterday afternoon I had a fantastic session with Ephemeral Structures. Although we have all worked with each other in several capacities, this is only the second time the group has performed in eight years. The result of yesterday’s session were pretty inspiring, so we are considering producing an album. The project includes Kyle Herskovitz (also know as DJ Zenrock) on turntables, Nils Westdal on bass and electronics, and me on electronics. The photo shows Kyle playing his turntable with a rubber band. I’ll share a segment of what we captured in a upcoming entry.

POSC Pocket Oscillator

Posted on April 19, 2010 by John C.S. Keston

This weekend I built a POSC Pocket Oscillator by Sonodrome as a prototype sound design element for an interactive dance collaboration. The circuit is incredibly simple, as you can see by the photo, but the variety of sounds possible with the two pulse wave oscillators is impressive. The first oscillator is controlled by by the players skin resistance between two zinc plated contacts, while the second is controlled by an LDR (light dependent resistor). Rather than running independently the first oscillation modulates the second.

After testing the build, I temporarily setup the POSC in a small cardboard box and started making sounds. During one test I found that a circuit could be made with two people. when one person touches one contact and a second person touches the other, then the people touch each other the circuit is made with a lot of resistance creating a much slower pulse. Here’s an unprocessed sample edited out of my initial experimentation.

Four Oscillator Drone Produced with the WSG

What good is a Weird Sound Generator if you’re not using it to make weird sounds? Sometimes it is nice to just hold it on your lap and stroke it gently. That aside, it’s quiet useful once you plug it in and start twiddling the knobs. Here’s a piece I created by tuning the each of the four oscillators on the WSG and then fiddled with the filters. At the same time I made some adjustments to a phaser that I was running it through in Ableton Live and topped it off with ping pong delay.

Exploring The Sounds of Ice

Posted on March 14, 2010 by John C.S. Keston

This is one of the coolest (no pun intended) sound design projects ever. Marlin Ledin rode his bike and camped around the Apostle Islands of Lake Superior covering about 150 miles on the ice recording the creaks and groans of the shifting ice plates. Listen to his recordings and checkout photos and videos of his expedition at www.bikingtheapostles.com. Marlin describes the ice sounds:

The Lake Drums, as some people call them, are an amazing phenomenon that rank right up there with Aurora Borealis. Lake drums, or drumming perhaps, occurs when a shift in the ice creates friction between sheets of ice, like tectonic plates of the earths crust. The unique sounds created come after these shifts in the ice. I ventured out and captured some of these sounds with modern recording techniques.

Superheated Water – Dance of the Blobs

I love the texture of this sound – it’s infinitely sampleable, and equally uncontrollable. A thin coating of oil, rubbed into the pan – then heat it on high for 5 minutes. After a while, the water becomes so hot and isolated from the surface of the metal it superheats (boils without bubbles). This creates the beautiful dancing effect you get, similar to when mercury is loose on a solid surface.

The recording was made on a fostex FR2LE with a canon digital camera for visuals. The single hits would be cool for super fizzy percussion, don’t you think? Sampled at 24/96 on a fostex fr2le in stereo, 12 inches above the pan.
