Colin Benders is looking for an alternative experience of electronic music. In the Recital Hall, he will present the first results of his research with an installation that can best be described as an electro-symphonic orchestra. His orchestra consists of modular synthesisers, each with its own sound and loudspeaker, spread across the stage, achieving a more spatial, transparent reproduction of electronic music, like that of a normal orchestra. The continuous performance is performed on a modular system, played by Colin Benders and a select group of musicians. Ahead of the world premiere of a larger composition in 2019, Benders works with a smaller version of his orchestra at the Holland Festival Proms this year. The system is capable of generating its own musical choices. During this nine-hour marathon session, Benders can investigate the unprecedented musical spectrum of this electro-symphonic orchestra, thereby blurring the boundaries between acoustic and electronic music. The audience will be able to come and go all day.
