Brief details of Performance: These works for percussion and live electronics explore the concepts of ‘imposed and mediated resonances’. In 'Deconstructions in Metal' an elaborate feedback system is set up between two large metal plates which have solid-core drivers and microphones attached at different locations on the surfaces of the plates. Feedback from one plate is imposed on the second plate and the resultant signal is returned to the first plate. The performer, in this case the Maltese percussionist Renzo Spiteri, interacts with the resonant processes by bending and flexing the plates. The second part of the piece explores more conventional percussion playing albeit with recycled pieces of metal. The same signal processing techniques are employed in this second section.

In 'Thin Air' the percussionist bows and plucks on a single string (fishing line) attached to the bottom of the plate. These sounds are picked up by a contact microphone on the plate, processed and returned to the plate via a solid-core driver. In addition, samples and textures are played back through the driver to the metal plate.

'Parallax', the most conventional of these three works in terms of resources and performance techniques, imposes the resonances of the drums onto a series of delay lines . Later in the work the delay lines become a physical model of metal plate and form a link back to the metallic timbres of the 'Deconstructions in Metal'.

These three works are part of a larger-scale programme performed by Renzo Spiteri and they have been performed in Belfast, Portugal, Malta and Dublin.

A portfolio of materials supporting this output has been supplied on CD/DVD.
