Scrapes (2004)
For feedback network consisting of microphones, loudspeakers and graphic equaliser.

Scrapes 1 is a work that examines the process of audible feedback. The technical set-up comprises of a 'figure 8' system whereby a set of two microphones and loudspeakers feedback into each other. Delay processors and a graphic equaliser are employed to delay and colour the feedback signal, whereby the performer can adjust the settings of these devices to implement changes in timbre and rhythm.
