Artist:Yamila Ríos + Joris Strijbos – COVEX
Date + Time: 28 September - 00:30 - 01:00
Location: city hall - sphæræ


Yamila Ríos and Joris Strijbos will perform 'COVEX' as part of the Sphaerae program, an extended cello performance interplays with a meticulous constellation of laser beams shot trough transparent objects.

'COVEX' is a collaboration between composer and sound artist Yamila Rios and visual artist Joris Strijbos. In this audio visual performance the duo researches the relations between electro-acoustic sound and diffracted light-patterns in a diagonal mixage between the two media. The sonic output consist of a live performance with an extended cello. The output of the instrument is used to create a mass of sound which morphs from a complex noisy environment of fast fragmented textures to a serene and harmonic drone. While a overall collapse of tempi within sound-structures is manifested, the sound of the cello is being revealed. Within the visual domain, a meticulous constellation is formed by shooting laser beams trough transparent objects. By doing this an effect known as the “speckle pattern” occurs, resulting in abstract landscapes of detailed colour patterns and dynamic evolving shapes.

Joris Strijbos is a Rotterdam-based artist, working in the fields of expanded (live) cinema, audio performances and kinetic-light-installations. He is one of the persons behind Macular, a collective which focus is mainly on the synaesthetic relation and interaction between moving image and sound. Starting of as a musician he released work on different international record labels and performed in many countries throughout Europe. Since 1999 he’s been running several record labels on which he releases all kinds of experimental electronic music. While de-constructing and reconstructing audio equipment for
his music performances, he expanded his live-set with obsolete and analogue video equipment. With a special interest in organic organizations and structures he nowadays creates computer software to generate visual complexity. These techniques re-appear in his installations, in which he focusses on the creation of emergent systems and their possibility’s for audio/visual composition.

Yamila Ríos is a Spanish composer, performer and sound artist base in The Netherlands. Her artistic practice deals with the creation of aural spaces. This ephemeral spaces are not fix or constant they unfold and change in time. Since time is a necessary parameter to explore space in her compositions she focus on both aspects, time and space. Her pieces consist of multiple textures, and masses of sounds. Each of them with his own internal and complex activity. She has been working on different projects and pieces, mixing live electronics and the sonic exploration of traditional instruments. As a performer she had develop an extension of her cello by attaching different sensors to the body of the instrument. Her works have been presented at festivals such as Sonic Acts (Amsterdam), Ars Electronica (Linz), In-Sonora Festival (Madrid), Seoul International Computer Music Festival, STRP Festival (Eindhoven), Electrogals Festival (Portland), Kontraste Festival (Krems), Contemporary Music Festival (Sevilla) among many others. Yamila holds a Bachelor and a Master in Sonology form the Royal Conservatory of The Hague.
