The Somethin’ Else Electronic Music Potluck

This Friday, June 11, 2010 is the first in a series of events put on by Jon Davis called The Somethin’ Else. This instance is subtitled Odd Couples and features duets that have one artist producing electronics with a second, in contrast, mostly acoustic player. The performers include the following:

Jon Davis & Elaine Evans
Brett Bullion & Chris Smalley (Burnsville)
Steve Goldstein & Scott Fultz
Tim Glenn & Jeremy Ylvisaker (Siamese Bug)
John Keston & Graham O’Brien (Ostracon)
Adam J To & Dejen Tesfagiorgis

The event is located at the Stevens Square Center for the Arts, 1905 3rd Ave S., Minneapolis, MN (above the 3rd Ave. Market). The music starts at 7pm and goes until 10pm. All ages are welcome. A $5.00 cover is optional if you bring food or drink to share. It’s a potluck!

I’m excited to be performing at the show with my project Ostracon (John Keston on electronics and Graham O’Brien on drums) at 7:30pm. Expect to hear some angular GMS layers combined with Graham’s on-the-verge-of-chaotic drumming.

Sound Builders: Inventor of Circuit Bending Reed Ghazala

I’m really enjoying the Sound Builder series on Motherboard.tv, but this episode is brilliant. Now if I could just get the real-time version of that sped up footage! For more about Reed Ghazala checkout his bio and sounds from his instruments on anti-theory.com.

The Visible Pocket Oscillator

I really love this instrument. It’s simple to build and operate, yet the variety of sounds possible is broader than you would expect. This is the third Posc I’ve built. The first one I assembled into a small cardboard box. Let’s call it the Cardboard Posc. I disassembled the Cardboard Posc to build a prototype sound object for a dance piece.

For my third version I decided to build it into a transparent plastic case, formerly packaging for my iPod Touch. Let’s call it the Visible Posc. Right now it’s held together with a rubber band, but I’ll probably replace it with a screw or something to open it up for battery replacement. For more checkout these posts:

Experimental Music Mondays Part 4

Part four of the Experimental Music Mondays series begins at 9:00pm on May 31, 2010 at the Kitty Cat Klub in Minneapolis with Heizerbaum & Panderton featuring Andrea Steudel from MinneapolisArtOnWheels.org, with sound artist Luke Heizerbaum (actually I don’t think that’s his real last name, but let’s go with it). Expect to see some fascinating projections including images from a microscope of a vinyl record as it spins on a turntable.

Next up is Ostracon (John Keston on electronics and Graham O’Brien on drums). We perform generative, improvisational compositions using the GMS (Gestural Music Sequencer), that converts video input into musical phrases. “Keston captures, layers, loops and processes melodic segments in real-time out of the stream of notes created by his gestural input, tailored with probability distribution algorithms. O’Brien accompanies these angular, electronic structures, with dynamic playing that, at times, verges on the chaotic. More about Ostracon can be found at audiocookbook.org and unearthedmusic.com.”

Closing the evening is Twenty Thirteen, “a trio, made up of Chris Robin Cox (Junkyard Empire, Minneapolis Free Music Society) playing electric trombone, Bryan Berry playing guitar through tons of effects and loops, and Kahlil Brewington laying down bad ass funky drums. The music is ambient, yet groovy as hell, and incorporates influences as diverse Portishead, Bitches Brew era Miles Davis, and classic hip-hop, drum n’ bass, and dub beats. It’s like nothing you have ever seen live. The band sometimes performs with a fourth member: a television, which sits facing away from the band, and channels can be changed by audience members; the band providing the soundtrack for a television they do not watch. It’s a bit of a social experiment.”

Saucer Sled Synth

Recently I built a Posc (Pocket Oscillator by Sonodrome) and discussed it in this entry with an audio example. Shortly afterward I built the circuit into a cardboard box and used the instrument in a number of performances and recording sessions. Now I have disassembled my beloved cardboard box and created a new instrument for an upcoming dance performance. This updated prototype is made from a plastic saucer sled, a 4″ speaker, a recycled nine volt amplifier, and the Posc circuit.

I started by drilling a grid pattern of air holes for the speaker. I then mounted the speaker behind the grid as shown. Finally I soldered the Posc circuit to the nine volt amp and the amp to the speaker. Two nine volt batteries and some duct tape completed the prototype. The night of the build I handed it to Pramila Vasudevan, the choreographer for the piece, and was amazed by the sound quality, and the response of the instrument to her movements. The final product will most likely be fabricated out of fiberglass to improve the rigidity and resonance of the disc or “shield”.

Read on to see a few more photos of the instrument.

Reminder About the GMS Generative Track Competition

I have received a few notices of intent to participate in the GMS Generative Track Competition, but no entries so far. The deadline is still May 31, 2010, but I may extend it if necessary. Please drop me a line if you’re intending to submit something, or need more time. Here’s the original entry that includes the details about the competition.

Korg Monotron First Impressions

Lately, as you might have noticed, I’m attracted to synthesizers that don’t necessarily use keyboards for input. The Korg Monotron is a $60.00 battery operated true analog synthesizer with a ribbon controller and five knobs to control pitch, LFO rate / intensity, and VCF cutoff / peak. The Monotron will be available in the US this July. For more details checkout this article on Synthtopia.com.

Read on for more Korg Monotron videos. The next one is especially good.

Frequency Modulated Drone Generator

I’m currently working on a sound design project for a client who is looking for a way to generate specific sorts of sounds using easy to understand controls. I started by creating a frequency modulated drone generator. The tool has a mixer with six preset pitches plus noise. I also included amplitude modulation, with sliders to control the amount, LFO, and a frequency multiplier to allow for FM synthesis effects. Here’s an audio example that illustrates the range of sounds possible with this set of fairly simple and intuitive controls.

In/Out 2010: Digital Performance Festival

I just got a note from the organizers of In/Out, an annual digital performance festival in New York that features digitally driven performances and workshops over two days at The Tank Theater in Manhattan. This year the festival is on September 17 and 18. If you’re unfamiliar with this inspiring event, checkout some of the video documentation. Read on for the details and submission guidelines.
