Multimedia concert "Shells"
Palazzo Novellucci
Prato, Italy, July 6, 2003
"Shells",
a piece for Tarogato (a traditional Hungarian single-reed wind instrument) and
interactive music system, was first written in 1993 by Robert Rowe in
collaboration with Esther Lamneck. The piece, about 10 minutes long, was part
of a concert lasting for about 1 hour. The Tarogato part includes notated and
improvised material. A dance improvisation is also performed on the music. The
computer analyses the Tarogato performance and adds drones, ostinati, and
counterpoint as the pieces progresses. At the same time, audio analysis
generates visual feedback by expressively manipulating both pre-recorded images
and the live images of the player and the dancer during the performance.

The EyesWeb open platform was employed for audio analysis and for generation of visual content in real-time. The visual content consisted of expressive manipulation (e.g., in term of colors, deformation, application of filtering techniques) of both pre-recorded material stored in avi files and live images of the player and of the dancer (Douglas Dunn) gathered by a webcam. The application was distributed on two laptops connected by an Ethernet network: the first one responsible of audio analysis and the second one devoted to video processing. Robert Rowe's Cypher system carried out a parallel analysis of the music performance and was employed for real-time generation of audio content.
