*In process of  stocking* The score for ‘Truth, exercise for a listener’ comprises a catalogue of options for a musical performer. In four parts each focusing on a different facet of our faculty to listen, it offers open ended material for the performer to deal with; sounding actions, silent actions, still actions, moving actions, interpretative actions. All can be selected, combined, omitted or extended at will. Multiple exercises can happen simultaneously. In a general sense the piece is an attempt to create a performance situation that instigates changes within and between the sound spaces we inhibit. Accordingly, it highlights listening as a process of continuously shifting perspective and forces such shifts with all listeners involved. Performers are instructed to actively engage with and -somehow methodically- measure, interpret, excite and derive cues from the acoustics and ambience of the different sections of a performance site. Public performances of the piece can not be announced beforehand and when recorded, only with a handheld device. The recording engineer then becomes a performer, equally inquisitive and documenting the space(s) that he/she moves through.
