Today we conclude our reports from the Battery Powered Orchestra Workshop (BPOW!!!) in Portland, focusing on the evening concerts. Like the workshops, which we covered in Part 1, the concerts focused on DIY technologies, as well as analog synthesis.

The Saturday-evening program opened with Stephanie Simek performing on her custom multi-armed turntable.

The arms on the turntable were outfitted with contact microphones which picked up vibrations from the grooves of hand-cut records. Each arm fed a separate audio channel, creating a multi-track, spatialized performance from a single record. Musically, the repeated sounds of jungles, space, human activity and instrumental sources formed complex rhythms with changing syncopations and graduation motion over time. The effect was quite hypnotic. Even with the enveloping sound system, there was something intimate about the performance, probably related to the visuals and distinct sound of the record player.

Simek was followed by F-DT (Future Death Toll). F-DT is an artist collective and performances feature a rotating lineup, but on this occasion it included Edward Sharp and Nathanael Thayer Moss. F-DT describe themselves as “a throbbing mess of noise that eats technology and shits performance art.” And it was certainly a performance filled with loud noise in a variety of aural ranges – high electrical noises and pounding low-frequency patterns – set against a relentless stream of glitchy visuals and text.

Although it is hard to tell from this photo, much of their gear was colored orange, which seems to be an important part of the group’s identity. The music and presents is undeniably challenging, but well worth for those who make the effort.

Then it was my turn to take the stage. My setup focused on the analog modular synthesizer, along with another analog synth, iPad, the dotara (Indian string instrument), and Skatch Box. I also used the Synthrotek 4093 NAND synthesizer that I built during one of the workshops earlier in the day.

The 4093 worked flawlessly, as did the modular and the Luna NT analog synth. The acoustic instruments (dotara and skatch box) also worked well. As with any experimental electronic improvisation performance, there were a few technical glitches and a few things I would have done differently in hindsight. But overall, I thought it was a good performance, and it was very well received by the attendees. You can see and hear it in its entirety in the video below:

The final act of the first night was Mechlo. His performance combined lo-fi glitch audio and video from an NES console.

Clearly, there were modifications made to allow the system to be performed in a way that a traditional NES could not. Nonetheless, the graphics and audio were reminiscent of what one would expect from the classic 8-bit games. There were repeated modulating patterns, some of them more melodic, some noisier, with occasional glitches and pauses.

The Sunday evening concert opened with a performance by analog modular virtuoso Jeph Nor with Dan Green on analog video. Green brought an LZX modular video system, while Nor had a large collection of audio modules from different manufacturers.

Nor built complex patterns of sound that went from sparse and resonant to thicker and more pad-like. There were moments of eerie ambience and others that had a machine-like precision. Overall, he was able to give his improvisation with this instrument a musical and even narrative quality. The visuals focused on patterns of colors, curves and lines that were constantly changing, but occasionally slowing to a standstill before shifting rapidly and switching to a completely separate collection of shapes.

Next was Mike Todd performing custom visuals and sounds. Unlike the sharper edges from Nor and Green earlier, or the noisy intensity from F-DT the day earlier, Todd’s performance was software and more organic. The visuals, based on his own software, were composed of curving liquidy shapes that seemed alive. Similarly, his music had an equally liquid quality, with more open space between fast elements, as if a swarm of moving organisms.

Todd was followed by JMEJ, who assembled sonic circuits live on stage. One can think of this as “analog live coding”.

The process was fun to watch. As one might expect, the sounds were a bit on the noisier and unpredictable side, but with a lot of good crunchy lo-fi texture. As the performance continued, the circuits grew more complex and culminated in this tangled product:

The final performance featured Claus Muzak performing some of his electronic-music compositions.

This was a more structured performance, divided into songs. His music had a strong rhythmic and harmonic foundation, realized with a diverse collection of synthesizer and drum-machine sounds. It was dark and richly textured, and at times danceable, especially when he employed rhythmic lines with high-Q filters. It was probably the most “traditional” of any of the performances on either night, well crafted electronic music that would be at home in a club setting. But it was a fitting conclusion for evening’s performances and for the festival as a whole.

Overall, both the concerts and workshops from BPOW were a rewarding experience. It would be great to visit again to participate in future events, and in the meantime I look forward to hearing more from the artists involved. Thanks to Travis Feldman of moleculesynth for organizing BPOW and Myles de Bastion of Cymaspace for hosting.
