11 August 2023: General rehearsal and Final concert


The sound of every instrument is being analysed and generates instructions forother players. The musicians interact and mutually control each other. The live generated instructions are communicated via iPads. The sound of the instruments is extended with live electronics.

Every performance of CONVERT EGO will sound different. The performers must have a high degree of personal commitment. They not only have to fulfil the role as a performer, but are also required to improvise and to take responsibility for compositional decisions.

The musicians move the music individually and in changing groups. On stage, all instruments will be equipped with microphones and will have a reference loudspeaker and an iPad.

There is a thin line between technically supported composition and improvisation: Perhaps a new approach to interpretation?
