Concert at Prisms Contemporary Music Festival, Phoenix, Arizona

Solo concert and improvisation with Simone Mancuso, Garth Paine, Justin Kennedy at the Prisms Contemporary Music Festival “Boulez Legacies:

Offering the highest-quality performances of experimental music in the Phoenix metropolitan area, the annual Prisms Festival is comprised of themed concerts and showcases music that is rarely performed, along with pre-concert talks, round tables, film screenings, and workshops. The goal of the festival is to promote the view that music is a living tradition – an exciting and vibrant part of modern life – and to pass on that belief by combining performances with informative lectures and discussions for ASU’s students, the local art and music communities and the general public.

The concert video is here, Diemo Schwarz’s solo piece starts at 1h15 after the intermission, followed by an improvisation with Diemo Schwarz (live-input CataRT), Garth Paine (flute), Justin Kennedy (Mongolian throat singing), Simone Mancuso (percussion) at 1h41.

Katzin Concert Hall, School of Music, Herberger Institute for Design and the Arts, Arizona State University, Phoenix, USA.

Camino del Sol Video and Documentation

Galerie Thaddaeus Ropac Paris Pantin
27 Nov 2014 – 10 Jan 2015

Sylvie Fleury presents Camino del Sol, a new sound and dance performance project at Galerie Thaddaeus Ropac Paris Pantin. The exhibition that follows reveals the set for the performance and some of its leftover materials.

Originally inspired by Fluxus performance, where simple, repeated actions produced sounds, Fleury’s performance, with its own aesthetic premise, incorporates gestures from everyday life revealing the vibrational presence of individuals. The set-up allows for the poetic, the sonic and sometimes the absurd to bloom.

Dirty Tangible Interfaces (DIRTI) are a new concept in interaction design that forgoes the dogma of repeatability in favor of a richer and more complex experience, constantly evolving, irreversible & infinitely modifiable.

Ircam Live with duo Hans Leeuw / Diemo Schwarz at Gaîté Lyrique, Paris

The duo of Hans Leeuw (Electrumpet) / Diemo Schwarz (CataRT) has been chosen as one of 4 winners of the Ircam Forum call for performances (out of 85 submissions) and will be presented in concert:

Ircam Live @ la Gaîté lyrique

also playing: Plaid (Warp), Lorenzo Bianchi, Benjamin Carey, Jean Lochard

Gaîté Lyrique, grande salle
3bis, rue Papin
75003 Paris

The duo between Hans Leeuw and Diemo Schwarz creates a dialectic between the age-old gesture of the musician and its digital transformation and critique, a pathway between the acoustic instrument and a recontextualising synthetic interaction at the heart of our times. The duo’s focus on expressive play with live sounds happens in two very different ways that happily blend together: Read the rest of this entry »


CataRT as an Instrument

Since about 5 years, CataRT is used extensively as a performance instrument by myself and other musicians, and has stabilised and been tried and tested in many performances.  This is why the Inventor Composer Coaction call for new instruments was a welcome occasion to present this instrument to a wider audience, and to advance towards a systematic assessment of how to play and compose with CataRT.

To this end, the CataRT as an Instrument page collects the links to sound and video examples demonstrating CataRT as an expressive performance instrument.
Since CataRT must be seen as a whole family of possible instruments, around the core concept of the timbral sound space that is played by navigation, the actual instrument is determined by the controller that steers the navigation.
