You are listening to Nylong Symphony, Part 5 (excerpt).
This half-program during the "String Theory" festival featured Oliver performing on multiple guitars and computer, the first version of his "Nylong Symphony" project.
Oliver is holding his hand in front of a light beam controller which controls the sound colour and behaviour of a (physical modelling) synthesizer which he plays using the classical MIDI guitar.
