Voice 2012

Seven years after our previous collaboration, Maja Ratkje and I got together for a performance in Johanneskirken in Bergen for Festspillene i Bergen this May. I created a setup using LED modules normally used in outdoor video walls which I placed in an arc behind Maja. The arc functioned both as a canvas for low resolution patterns but also a powerful light source affecting the whole church giving me an opportunity to modify the whole space by improvising with these screens.

We have been invited to perform at the Bozar Electronic Arts Festival on september 22nd  (Bozar, Brussels) and later at the Kontraste Festival in Krems in october.

Johanneskirken has probably never looked cooler from the outside:

7 cirkler

Last year I was asked by curator Morten Søndergaard if I wanted to contribute to  “Unheard Avangarde” which was to be a section in the big sound art exhibition at ZKM (which opened end of March 2012). The idea was to combine contemporary artists with works by pioneer composers of electronic music in Scandinavia. I was initially reluctant, but after hearing the music I was sold. I was asked to work with the composition 7 cirkler by the Danish composer Else Marie Pade, which she made in 1959. She was inspired from visiting the planetarium at the Brussels World Expo in 1958, and using tone generators and tape she created a system of building up layers (circles) of sound and then reversing the process and end up with just one circle again. Here is a diagram showing how she constructed the composition:

I was interested in making a similar structure with circles of light animations combining into more complex light-shadow patterns.

The installation is on display until January 2013 at ZKM

multimorf 3: a composition for trombone and waterfall

I just finished a new collaboration with composer Knut Vaage, Multimorf 3, a composition for waterfall and trombone.

The image above is a snapshot from each of the nine sections of the piece.

The trombone plays together with recordings of waterfall and layered trombone overtones (also combined with live processing of the trombone).
The composition has an open form:
Vaage has together with sound designer Thorolf Thuestad created nine morphed backgrounds of waterfall recordings and trombone overtones. The trombone player, John Arild Suther, chooses how long each morph section should be played and in which order they should be played, as well as which sections of the composed score he wants to play within each section. This opens for very different performances based on the same material.

The video is conceived in a similar way to the morph backgrounds. The material is based on waterfall recordings and generated material, and each of the nine sections can be viewed as individial motion paintings. My intention was not to create something that followed the music directly, but to create a visual component that responded to the energy contained in a waterfall and to reflect the individual qualities of the nine sections. Since the length and order of each section can vary for each performance, I wanted each section to focus on layers instead of creating linear trajectories: If you see thirty seconds or four minutes of a section you will get more or less the same visual content, it is the combination and length of the different sections that create the linear dynamic of the piece.

The trombone player controls both the playback of video and sound backgrounds, using midi foot pedals, making it relatively easy to tour with the piece without involving too many people.

Multimorf 3 premiered on August 12th at Baroniet in Rosendal (probably one of the most beautiful places in Norway). We played outside in the courtyard of the Manor from 1665 to an enthusiastic audience.

It will also be performed at Bergen Architechture School on September 1st (together with multimorf 2), and at Integra in Copenhagen October 1st.

Two new works

I have made two new works for my exhibition at IMAL, which is my first solo show in Belgium (29.04-22.05.2011).

As in my recent installations blink and split I am interested in relating directly to the architecture of the exhibition space. The main IMAL space is about 200m2 with a grid of 12 columns.  The circular discs are freestanding sound modules (five in total) placed on the floor. A slowly-paced sequence of projection and sound transforms the space into a contemplative environment.

The other installation explores through projection,light and reflection the inside,outside and perimeter of a circle mounted at a 90 degree angle to the floor. This is a first in a series of work creating dynamic volumes out of precisely cut flat shapes (in this case using a cnc mill).

For more images (also in print quality) from both installations take a look at my flickr set from the exhibition.

Results from openLAB exhibition at IMAL

In beginning of April IMAL hosted an openLAB workshop called “Projections on forms and spaces”.
The workshop was led by me and was mainly based on using VPT. We selected 7 projects to be realised during one week development at IMAL, and the documentation is now available from IMAL.

It was an intense and interesting week, and interesting to see VPT explored for new uses in installation and performances. A new development for me was to introduce a simple video and audio trigger setup (available in the xtension section), which allowed for some audience interaction, as well as use of the serial module for controlling lights inside sculptures.

VPT 5.1 available

After nearly 2500 downloads of the first version of Video Proejction Tools VPT 5 released in december 2010, I am happy to announce the new version 5.1, partly based on feedback from workshops and the VPT forum.

The release focuses on all the possibilities to expand and customize VPT to be the right tool for your particular project.

This includes a vastly improved controller section, making it possible to control almost every feature of VPT from another application (like maxmsp, processing and PD), computer, sensors through the arduino microcontroller, midicontroller as well as built in lfo controllers for automating control and software sliders and buttons. This comes on top of the already existing built-in preset and cuelist system for playback. Through OSC, VPT parameters can relatively easy be controlled by gestures, using camera or kinect tracking.
You can easily set up VPT to control simple projector shutters by controlling servomotors using the arduino module.

Templates are provided with the download for exploring OSC on maxmsp and Processing, PD will follow later. Arduino templates for input/output as well as a servo example is also included with the download.

VPT can be used with multiple projectors using Matrox Triplehead2go, and the latest version also includes support for multichannel sound: The movie sources can be individually routed to up to eight channels, depending on your sound card. Using the provided maxmsp template it is possible to process the sound further.

VPT 5.1 includes a new possibillity of processing the sources using the FX bus. The FX bus consists of eight FX chains, modules which contains shader based effects. New FX chain modules can easily be made using the provided maxmsp/jitter template, and can be dragndropped onto the existing FX chain to replace it, making it easy to customize the effects to your particular need.

Three new sources have been added to VPT: A solid (if you just want a colour in a layer), a noise texture generator and a text module which can either use text from file, osc or typed text. A maxmsp/jitter template is also provided if you want to create your own source.

VPT templates and examples for maxmsp/jitter, PD, Processing and Arduino

VPT is a free multipurpose realtime projection sofware tool for Mac and Windows developed by HC Gilje. Among other things it can be used for projecting video on complex forms, adapt a projection to a particular space/surface, combine recorded and live footage, or for multiscreen HD playback.
