Dieb13, Djll, Greenlief, Robair, and Ueno at CNMAT

Last Thursday, I found myself back at my old “stomping ground”, the Center for New Music and Audio Technologies (CNMAT) to hear an evening of improvised music.

Dieb13 (aka Dieter Kovacic) opened with a solo set for multiple turntables. It started with a single turntable producing noise/static sounds, and gradually incorporated electrical hums and synthesizer sounds, along with complex repeated rhythms. The rhythmic patterns were sometimes metric, sometimes more stuttering. With three turntables going at once, Kovacic’s performance seemed more “synthesizer” and less “DJ.”

Dieb31 was then joined by Tom Djll (trumpet and electronics), Philip Greenlief (saxophone), Gino Robair (percussion and electronics) and Kenn Ueno (extended vocal techniques). The set began with “scraping sounds”, Robair blowing a small horn against a drum and Greenlief scraping a mouthpiece cover along his tenor sax. Indeed, the acoustic instruments as noise sources dominated the first section of this extended improvisation, before the Blippo Box, the other electronic instruments and Dieb31’s turntables entered. It was interesting to hear how the sounds from the turntables an Ueno’s vocal techniques matched the acoustic instruments, and it was a challenge at times to tell which sounds were acoustic and which sounds were electronic.

Another notable confluence was Ueno’s throat singing set against low-frequency sounds from the turntable and the Blippo Box. There were also contrasting sections with percussive short notes on all the instruments (trumpet, electronics, sax, voice, turntable, percussion) in rapid succession. There was a very soft section with saxophone multiphonics (we have commented on Greenlief’s expertise with multiphonics in the past), vocal whispers, low-level electrical sounds, and a resonant tube; and very loud moments, screeching, high-pitched. One very rhythmic section featured Gino running fan against cymbals and Tom Dill running a similar fan against his trumpet. Greenlief joined in running keys against his sax. The piece ended with loud notes that came to a sudden stop.

This was followed by a much shorter “encore” improvisation, whose memorable moments were the variety of sounds from the turntable, which included an excerpt from a bebop recording and a toilet flushing.

Weekend events in San Francisco (Music, Art and Cats)

Another busy weekend, especially with the number of things going on. We only have time for a partial review…

First, there a quick stop at downtown pub to see some friends/colleagues. Then a rush to BART to get across the bay to Berkeley and my old stomping ground, the Center for New Music and Audio Technologies (CNMAT).

I was a few minutes late, but still had plenty of time to hear Joker Neils and Gino Robair performing a improvised duet. Robair has an amazing talent for getting electronic-like sounds out of acoustic percussion instruments, and did so again on this evening. Neils was primarily using custom synthesizers, both professional instruments as well as circuit-bent toys. We have discussed circuit bending previously here at CatSynth. He brought several well-crafted examples, including Suziki Omnichords with contact-resistance interfaces; and he also brought a tremendous enthusiasm to his performance and to his discussion of circuit bending in between sets.

Also presenting was Rob Hordijk, who designs custom synthesizers (or “works of art” as he described them). Among the technologies he employed in the “Blippobox” that he presented were chaotic oscillator pairs, where two oscillators feed back into one another to create non-linear modulation, and a filter that he called the “twin peaks” filter (presumably because it has two resonant peaks).

Amy X Newburg lent her vocal and electronic-music talents during the presentation and in the second half of the show – readers may remember her from a a recent music festival that we reviewed.

I had some interesting conversions with both Amy X Newburg and Joker Neils following the performances, which is always a nice coda to a concert.

It was another exceptionally warm weekend in San Francisco (I wouldn’t mind it becoming less exceptional), so more opportunities for walking events. First off I finally made the trip to the San Francisco SPCA to inquire about volunteer opportunities and see their much touted adoption center. The cat area featured large rooms, “kitty condos” as well as comfy areas to hide – it actually seemed on par with the “cat resorts” where I looked into boarding Luna. The SPCA is actually a short work away from CatSynth HQ (well, it’s at least short from my perspective).

Another short walk in the opposite direction from CatSynth HQ led to the Yerba Buena Gallery Walk. Open studios and gallery events are pretty regular occurrences, even within walking distance. Plus, there’s often free food and drink. I didn’t see too many things that truly interested me, except for some abstract paintings at 111 Minna that I had already seen during the first Thursday earlier this month. But that doesn’t mean the afternoon wasn’t without its attractions. Some of the galleries, such as Varnish, were in very interesting spaces, such as converted industrial buildings from the early 20th century. A view of Varnish is in the photo to the left. Additionally, some of the sights on a gallery tour aren’t the works of art, but the people viewing them – and this is even more true on a warm sunny day. Finally, I did have a delightful conversation with Jesse Allen at Chandler Fine Art – his very psychedelic/natural works aren’t what I am usually drawn to, but some of them did include abstract representations of cats and other animals and one “wild cat” in particular caught my attention.

More art on Sunday, this time photography. This Sunday was “Pinhole Photography Day” (who knew?) and the RayKo Photo center featured an exhibit, demonstrations, and most notably a ride on the Bus Obscura a school bus converted into a large camera obscura.

The bus obscura toured our South-of-Market neighborhood, providing a unique view via the pinhole-camera images. Small dots of blurry light would suddenly come into focus as a sidewalk or car or storefront.

Because the image were so localized, it wasn’t always clear exactly where the bus was, though every so often a familiar landmark would emerge. The ride was accompanied by live acoustic and electronic music, adding to the experience and making it different from the regular “tours” of our neighborhood.
