recordings 2010-2011

In December and January I recorded all the commissioned works from my research project on a CD, and a separate CD with improvisations, together with Peter Tornquist. Mats Claesson, from the Academy of Music is the sound engineer on these productions, and also does most of the mixing. We work together to find the best cuts, and then he does the final mixing.

January 27 Diemo Schwarz came to the Academy and did a 3-hours recording session, improvising along his beautiful electronics. It was really cool to do this recording with him, and to make a suitable setup for CataRT, sending out the lines from the electronics separately. I used all my guitar gear, especially playing around with my Angel Dust-pedal (distortion and noise), which I borrowed from John Hegre.

Mats Claesson is editing and mixing/remixing the favourite parts of the recording this week.

Concert, Sound of Mu, January 25

The stage was set for an exciting encounter between two live electronic musicians of international standing at Sound of Mu on Tuesday January 25.

Diemo Schwarz from IRCAM held a workshop in advanced synthesis and signal processing at NOTAM in the end of January.

Diemo Schwarz is one of the leading figures within the live electronics field, and he has developed a number of signal processing tools, including Max/MSP patches such as FTM and CataRT. It was a pleasure for me to be able to play a concert with him again.

Schwarz-Johnson at Sound of Mu

The concert was organized by me in collaboration with NOTAM, and Cato Langnes was the sound engineer. In addition to improvisations by Diemo and me we

both played a solo piece each. I played Thomas Dahl’s piece No Reason Aftermath. It was a great atmosphere at the venue.

Diemo is using the iPad as a control function for CataRT, as well as a pressure-sensitive MIDI-controller which controls the dynamics. It works so well with the iPad. He can play it like a separate instrument, away from the computer, using the accelerometer.

Concert September 3, 2010

At the concert, Alexander Refsum Jensenius and I performed our piece Transformation, exploring improvisation in time and space during this concert that also featured pieces by Henrik Hellstenius, Thomas Dahl and an improvisation by Victoria Johnson and Peter Tornquist.

Alexander and I have been collaborating for several years on exploration of various types of technologies for musical expression. The piece currently presented is based on video analysis using modules from the Musical Gestures Toolbox in Jamoma and CataRT.

By moving inside a seemingly empty space, I have slowly explored a sonic landscape of thousands of short fragments of various violin sounds. The space thus becomes a musical entity in itself, a space that the violinist both controls and interacts with at the same time. What seemed to be an empty space at first, is left as a sonic space in our memory when the piece ends.

For Victoria Counting IV we used the new visual ideas from the workshop (see previous posts), and added a new direction, made mainly by Henrik Hellstenius. The new direction made me very busy on stage, at first sitting on a low stool, after a while started to run when playing, and looking for my lost photos when at the same time looking at all the photos from my life.

video-analysis and spatialisation

December 9&10 I worked with Alexander Refsum Jensenius in video-analysis and Catart again. The theme for the workshop was spatialisation. Alexander had recently been to Denmark working with Dan Overholt on the same issue so we tired out a new patch called grid they had worked on together when he was i Denmark. We used spatialisation using V-bap and video-analysis tracking my position at the floor. And then we managed to let the sound follow me when I walked around in the space. We also did an experiment in Catatrt using homogeneous sounds like pizzicato  and instead of the preset chop we tried silence segmentation. That did nor work that well because the grain got a sot of delay (The patch s looking for silent zones) The evaluation of that preset is that I can  not control the sound with my movements.

We also tried to use 2 sound corpus’s in Catart and one grid-patch and reverb for maximum expression and sound in the room. That worked well. I think we are getting nearer what we want to achieve using the space. The next theme will be how to start with an empty space record sound  in Catart in realtime and then interact with the sound in the space.

Autumn 2009

I have also participated in the conference Sensious Knowledge at Solstrand, Bergen (September 23-25) and made a presentation in International Contemporary Music days in Gothenburg (October 2-3 rd 2009) During the seminar at Solstrand we heard many interesting presentations, but the most interesting thing was for me to meet other artist outside my field. In the conference in Gothenburg was about the boundaries of interpretation and practical Artistic research and was very interesting for my project. I did the presentation together with Henrik Hellstenius. I also played some excerpts of Victoria Counts II during the presentation.

Video-analysis and CatArt

Having the second workshop together with Alexander R Jensenius (October 5-6) has given me more understanding about how CatArt works. Again using a fairly big space at the Academy (4x4m) gave us the possibility to go through many different parameters in CatArt to evaluate what works the best. In this space it works best if the grains are fairly evenly distributed like in preset 2: Spectral centroid periodicity Loudness. Using this preset I am then able to use the whole space to interact. It also works best if the sounds we use are not too brutal and strong. (crush does not work so well as pizzicato and flageolets)

Working with open form

October 7-9 we had rehearsals for the open form festival in November practising Else Storesunds piece Liquid Vapour. The piece is based on schemes and graphs from a research book about water. We use these schemes as a starting point and ground for improvisations where the theme is water.

hyperimprovisation seminar

I arranged in cooperation NMH an international workshop on hyperimprovisation where the theme was; own practise with real-time improvisation and augmented instruments. The seminar took place at NMH during Ultima festival from 15-17 September 2009.

I have during the conference met some of the best international performers working in my field. I made a presentation of my project during this conference and got a lot of important feedback. I had the possibility to discuss musical, aesthetical and technical questions more informally with the participants during the seminar. To put the music, improvisation own practise and interaction with the computer as the main topic has been missing in many conferences such as NIME and ICMC etc.

I hope to arrange this seminar on annual basis and refine and sharpen the topic.

I have got written feedback from the participants and this feedback will be important for forthcoming seminars.

Participants: Victoria Johnson, Cléo Palacio-Quintin, Øyvind Brandtsegg, Peter Tornquist, Hans Tammen, Jan Schacher, Alex Gunia, Bjørnar Habbestad,
Tanja Orning, Natasha Barrett, Kjell Tore Innervik, Alexander Refsum Jensenius.

videoanalysis

IMG_5695August 24 and 25 I had a workshop with video-analysis together with Alexander R Jensenius. Based on his research he made patches which could track my movements in a room. I used the sound to interact with recorded material from the violin. We used a big space ar the Academy hanging a web-camera in the roof.

audiovisual satelite

On May 7th Mattias Arvasstson and I had our performance at the Museum of contemporary Art in Oslo. We tried out the idea of using the movement, colours and pulsation of the video as a musical score, using Mattias,s object for projection. That meant that we did not have to have any walls for projection and did not have to interfere into the exhibition as such. Originally it had been the meaning that the concert installation should take place in the big exhibition room. It is very light in Norway during the summertime and i realised that during one of the visits to the museum that this room was much too light for projection.IMG_5222 We ended up to get a beautiful empty room at the second floor. Many thanks to Anna Lindblad at the the Museum of Contemporary Art who helped us to get this space and to arrange the concert.

On photo: The original space for the performance.

For the first time I played a concert without any soundperson there. I realised that the acoustics changed  a bit when the audience came, and I think I will bring a stage monitor for the next performance. I used 6 genelecs, one on the object and the one with pure violinsound behind  me, and the rest in in each corner. Again I used the a granulation process using 3 buffers with different lengths, pitching and grainlength. Thanks to Edvin Østvik for the beautiful and user-friendly maxpatch !We had to carry all the equipment ourself which was really hard!

After rigging up we got visitors from the Academy of music, the electroacoustic composition class came to see what we where doIMG_5253ing.

On photo: The performance space

Having 9 footpedals I got a very broad setup. I am looking forward to experiment more with some smaller controllers and setup.

I will also for the next performance have visual monitor in order to see the visuals better.

Satelite on the top of the opera

opera_snohetta

It has been a very busy but interesting process working and performing the two Satellite concerts. The first one taking place at the Roof of the Norwegian opera and Ballet April 28 and the second one in a beautiful big space at the Museum of contemporary Art. Being in charge of the planning of the operaroof I had to go into the topic of projection, choice of lenses, amount of ansilumens when the goal is to have the projection as clear and big as possible. The size of the wall we wanted to project on was 14.5x 32 meters, and sunset was around 9 pm. I decided to go for 10 pm and hoped for good weather. I also had a “bad weather plan” hiring party -tents, but fortunately I did not have to go for that. On the actual day it was some scary black cloud, but it never rained! A bit cold though about 10 degrees.

To rig up PA and projectors took more planning than I would have thought. It felt like having a concert on the top of a mountain except that we had access to electricity.  I got very good support and help from Knut Vik and lot of people from the Academy of Music helped to rig down after the concert. I had decided because of the wind not to use music but have it on a PDF on the computer. Ivar Frouberg had made me a beautiful little maxpatch that could turn pages. I worked very well and secure. I was practising with the patch for about a week, in order to be able to use the foot for turning the pages (Yamaha midi FC) as well as using other pedals (fuzz, octaver, delay) For Elektra I also had to follow the maxpatch (triggers and timing) on another computer. All this technical issues worked out very well, although I from time to time during Elektra was very busy!

To get the projection as big as we got it worked out well, surrounded by the city on the big marmoreal roof. The volcano in Elektra became huge, and I became very small, which I see as an interesting contrast. The fact that the size of the projection was so big made a better communication between the music and the video. At the most I think it was around 400 people at the roof, something I founded very good.

Thanks to Ellen Roed who took some photos!

I got a lot of press on the project, also at Østlandsendingen (TV)

ftm workshop and concert

Rehersal with Diemo Schwarz at BEK

March 9-13 I participated on a FTM workshop at Bek in Bergen led by Diemo Schwarz from Ircam. A very challenging but interesting workshop. FTM is an extension for Max/MSP and PureData providing a small and simple real-time object system and a set of optimized services. (http://ftm.ircam.fr/index.php/Main_Page) Towards the end of the workshop he also went through Gabor and CaraRT.  In Gabor I founded some really interested pre-programmed patches I want to try out. Friday 13.3 I played a concert at Landmark together with Diemo Schwarz. He first had a soloimprovisastion followed by our improvisation and then the soundartist James Webb performed. During the stay I also worked with Thomas Dahl creating some new soundscapes for our piece. He used some of his favourite filters and features in Ableton. I think we have some really interesting material now; I just have find time to work and develop sounds and practice with the midipedal.  I want the pedal for to feel like an extension of my instrument so every move become smooth and sensitive.
I also worked with videoartist Mattias with our realtimeimprovisation concept. He is now using a “box” to project on. It feels much more like a symbiotic connection between audio and visual when we both relate to the visual material on the box.
On March I rehearsed with Diemo Schwarz at Bek. It was really interesting. I hope I can put some sound out in a while.
