I am honored to have been awarded a commission and residency at the 2019 Sampo Composition Competition, organized by musinfo.Following this award, I have composed a new piece Masse pétrie for cello and the live electronics system Sampo, which will be performed by cellist Marie Ythier. She has worked with many composers, and has recorded new works for cello and live electronics in her album Le Geste Augmenté.I'm looking forward to working with her, and to meeting the festival guest composers.What is the Sampo?The Sampo is a live electronics set-up that implements a simplified version of one algorithm available on the Lexicon sound processor LXP-15. Although the Sampo hardware is quite advanced and expensive (it includes a computer and a sound card), the software's capabilities are more limited than these offered by the original LXP-15 sound processor.

Petrified is a composition for double bass and live electronics. Bassist Will Yager premiered the piece during our Spring 2019 Laptop Orchestra concert. In this first version, I performed the live electronic processing live. Will asked me to prepare a standalone version that he could take on the road. Here is a screenshot of the live audio processing interface: In this work, the electronics consist of two layers:live spectral processing of the double bass, including pitch shifting, frequency shifting, noise shaping, etc.multi-playhead sampler, applied to sound sampled at different points during the piece.These sonic layers are also mixed with the direct sound of the instrument, and sent to a delay and two reverb lines.Tonight, Will is performing Petrified with the standalone live electronics, during the Electronic Music Studio concert, Stark Studio, Voxman Building, 7:30.

This semester, I've been coaching bassist Will Yager and soprano Anika Kildegaard on their chamber music project LIGAMENT. They have been building a great repertoire of pieces for double bass and soprano. Then, we had the idea of working on Pascal Dusapin's composition Anacoluthe, for soprano, double bass, and contrabass clarinet. Last week, during Ensemble Accroche Note's residency at the School of Music, we worked with clarinetist Armand Angster and soprano Françoise Kubler - she took the pictures. We are performing Anacoluthe tonight, at the School of Music, University of Iowa, at 7:30 in the Recital Hall. You are invited!By the way, do you know what an anacoluthe is?
