Regents Lecturer Concert, CNMAT (March 2011)

Today we look back on my solo concert at the Center for New Music Technologies (CNMAT) at U.C. Berkeley back in early March. It was part of my U.C. Regents Lecturer appointment this year, which also included technical talks and guest lectures for classes.

This is one of the more elaborate concerts I have done. Not only did I have an entire program to fill on my own, but I specifically wanted to showcase various technologies related to my past research at CNMAT and some of their current work, such as advanced multi-channel speaker systems. I spent a fair amount of time onsite earlier in the week to do some programming, and arrived early on the day of the show to get things set up. Here is the iPad with CNMAT’s dodecahedron speaker – each face of the dodecahedron is a separate speaker driven by its own audio channel.

Here is the Wicks Looper (which I had recently acquired) along with the dotara, an Indian string instrument often used in folk music.

I organized the concert such that the first half was more focused on showcasing music technologies, and the second half on more theatrical live performance. This does not imply that there wasn’t strong musicality in the first half or a lack of technological sophistication in the second, but rather which theme was central to the particular pieces.

After a very generous introduction by David Wessel, I launched into one of my standard improvisational pieces. Each one is different, but I do incorporate a set of elements that get reused. This one began with the Count Basie “Big Band Remote” recording and made use of various looping and resampling techniques with the Indian and Chinese instruments (controlled by monome), the Dave Smith Instruments Evolver, and various iPad apps.

The concert included the premier of a new piece that was specifically composed for CNMAT’s impressive loudspeaker resources, the dodecahedron as well as the 8-channel surround system. In the main surround speakers, I created complex “clouds” of partials in an additive synthesizer that could be panned between different speakers for a rich immersive sound. I had short percussive sounds emitted from various speakers on the dodecahedron. I though the effect was quite strong, with the point sounds very localized and spatially separated from the more ambient sounds. In the video, it is hard to get the full effect, but here it is nonetheless:

The piece was implemented in Open Sound World – the new version that primarily uses Python scripts (or any OSC-enabled scripting language) instead of the old graphical user interface. I used TouchOSC on the iPad for real-time control.

I then moved from rather complex experimental technology to a simple and very self-contained instrument, the Wicks Looper, in this improvised piece. It had a very different sound from the software-based pieces in this part of the concert, and I liked the contrast.

The first half of the concert also featured two pieces from my CD Aquatic: Neptune Prelude to Xi and Charmer:Firmament. The original live versions of these pieces used a Wacom graphics tablet controlling OSW patches. I reimplemented them to use TouchOSC on the iPad.

The second half of the concert opened with a duo of myself and Polly Moller on concert and bass flutes. We used one of my graphical score sets – here we went on order from one to the next and interpreted each symbol.

The cat one was particular fun, as Polly emulated the sound of a cat purring. It was a great piece, but unfortunately I do not have a video of this one to share. So we will have to perform it again sometime.

I performed the piece 月伸1 featuring the video of Luna. Each of the previous performances, at the Quickening Moon concert and Omega Sound Fix last year, used different electronic instruments. This time I performed the musical accompaniment exclusively on acoustic grand piano. In some ways, I think it is the strongest of the three performances, with more emotion and musicality. The humor came through as well, though a bit more subtle than in the original Quickening Moon performance.

The one unfortunate part of the evening came in the final piece. I had originally done Spin Cycle / Control Freak at a series of exchange concerts between CNMAT and CCRMA at Stanford in 2000. I redid the programming for this performance to use the latest version of OSW and TouchOSC on the iPad as the control surface. However, at this point in the evening I could not get the iPad and the MacBook to lock onto a single network together. The iPad could not find the MacBook’s private wireless network, even after multiple reboots of both devices. In my mind, this is actually the biggest problem with using an iPad as a control surface – it requires wireless networking, which seems to be very shaky at times on Apple hardware. It would be nice if they allowed one to use a wired connection via the USB cable. I suppose I should be grateful that this problem did not occur until the final piece, but was still a bit of an embarrassment and gives me pause about using iPad/TouchOSC until I know how to make it more reliable.

On balance, it was a great evening of music even with the misfire at the end. I was quite happy with the audience turnout and the warm reception and feedback afterwards. It was a chance to look back on solo work from the past ten years, and look forward to new musical and technological adventures in the future.

This one in via Silent Strike who composed the tracks for the app with a Clavia Nord Modular 1, Micron Alesis, Jomox Mbase, Reason 4 Propellerheads, M-audio Axiom 25, Elektron Drumachine (pic at the bottom of this post). The app does not allow you to manipulate sound, but I thought it was interesting to acknowledge some of the gear used to create the audio for this app. The Waldorf Blofeld and Yamaha AN200 pictured however were not used.

Looks like Silent Strike had a studio supervisor involved.

There is also info on the app itself.

Gravitarium 2 combines music, art and science in one relaxing experience. Use all your fingers to guide the star flow. You can create 10 different animations depending on the number of fingers touching the screen:

1 – Rocket, 2 – Sparkle, 3 – Energy flow, 4 – Atomic, 5 – 3D freeze, 6 – Circularium, 7 – Fish, 8 – Vortex, 9 – Lasers, 10 – Lightning.

Use different options to create spectacular drawings made of stars. You can load the “Drawing” preset from the “Options” screen.

I will be taking a look at this app. The idea of creativity and relaxation does appeals to me, but the game-play part is a bit less exciting – though it is the trend in the mobile-app space.

Ivy Room: The Final Hoot

Wednesday, May 18 was the final installment of the long-running Ivy Room Experimental/Improv Hootenanny series. It’s a bit sad to see it go, as I quite liked this home of weird music, mixed drinks and eclectic European-inspired decor. The evening was curated by Kattt Atchley (who together with Kenneth Atchley shared the bill with my quartet at the December Hootenanny). It was a very diverse program, ranging from experimental video to ambient electronics to “heavy metal jazz.” Special “cocktail menu” programs were provided. Here you can see the program next to a Manhattan, part of my personal ritual at these events.

The evening opened with Kerry Laitala presenting her appropriately named “Chromatic Cocktails”, selections from her 3D video work. Audience members were provided with 3D glasses for the full experience.

Among the pieces were two premiers, Chromatic Cocktail 180 Proof and Chromatic Reveries performed with live music accompaniment by Kenneth Atchley. These pieces focused on abstract shapes with undulating colors and motion, although Chromatic Cocktail 180 Proof also included realistic images if women that appeared and vanished within the abstract context. In Pin-Up in 3D, the figurative elements (short animated silhouettes of classic pin-ups) are more integrated into the abstract in that they are part of the chromatic effects

In the past, I have seen a video of Laitala’s that featured cats, though I did not see that in this set.

The overall experience of Laitala’s videos was mesmerizing. The images are their own universe with their own consistent rules about how color and motion work, so the viewer is naturally drawn in to process the entire experience. The source material is simple enough that it provides interest without getting in the way. Similarly, the music was abstract enough to enhance the feel of chromatic and spatial movement within the pieces without imposing a strong sense of narrative. Although the pieces took advantage of digital technology, there was something decidedly retro about her images – there was both the sources (such as the silhouettes of models) and the colorization effects that make it seem like it could have been part of a 1960s background film projection.

Kenneth Atchley followed with a solo set of ambient electronics. His sounds incorporate more harmonic ambience, noise, and some very distinct and punctuated synthesizer sounds. What I find interesting to listen to are the different levels of these elements, where a harmonic pattern seamlessly gives way to a section of more timbral interest. It is a little challenging to listen in detail in a crowded bar environment, however, and as such more ambient music becomes part of the environment and vice versa.

The final set of the evening, and of the series, was Go-Go Fightmaster, an ensemble featuring Aaron Bennett (saxophones and drinking straw), John Finkbeiner (guitar and drinking straw), Vijay Anderson (drum set), Lisa Mezzacappa (contrabass), Aram Shelton (saxophone), and Cory Wright (winds).

The set could be described as “avant jazz,: which veered between more experimental and more idiomatic styles over several pieces. There were very loud, punctuated percussive moments, and others where more expressive rhythmic patterns. The rhythmic sections tended anxiously build up in volume and complexity before getting software – a pattern I often hear in experimental jazz – rather than settling into a particular groove. With at times as many as three saxophones playing at once, along with guitar, bass and drums, there was a lot of energy – indeed quite aggressive and expressive at the same time. I don’t recall seeing any drinking straws. With punchy, staccato cadences and endings, this was a perfect conclusion to the series.

And so it ends. Thanks to Lucio Menegon, Suki O’kane, and others who have made the 14 installments of this series possible. So this leaves us with the question of where to go next? I have seen my share of experimental music series (and experimental-music-friendly venues) come and go. And as some disappear, new places emerge. But I think it’s important for us have a series and venue that isn’t too severe, where one can enjoy a nice cocktail while listening to weird music. The current thinking is for a Monday night series, “definitely not before September, and definitely involving fermented liquid.”
