Instrumentation: for string quartet

This work lives from a sonority rising from an environment of whispered tremoli and the slightest of tonal movements. Ascending to multi coloured sotto-voce effects and dialogues spoken under breath eventually falling back to the soft vibrations of the beginning. It is signed over to Janus, and so it develops around a short intermezzo, two strings whose affinity is audible but who have absolutely separate lineaments; where it comes to refined sound effects in Face I, Face II departs into melodic developments and contrapuntal associations…(NZZ)

Instrumentation: for violin and orchestra (2(2pic).2.2(2bcl).2/2.2.1.0/2perc/str)

“….a fantasy full discourse between the pre-existing and the powerful tradition of the virtuoso concert. It centralises the soloist, a soloist who multiplies and finds himself in partnership with five subsidiary soloists who, from various parts of the concert hall, offer support. Even the orchestra is not the collective against which the soloist stands out - it presents itself much more as a group of individuals who act, in certain parts, even independent of the conductor….”

Duration: 13' 00"

Instrumentation: for sixteen string instruments and percussion (9.3.3.1/2perc)

Sixteen solo strings are separated into chamber music groups and arranged around the percussion ensemble. From a light relaxed transparent sound surface and rhythmically pulsating figures, there develops chordal and melodic but also harmonic coloured structures which, like coloured glass splinters in a kaleidoscope, continually produce new combinations. Single soloists and small formations are set against each other resulting in an interplay between effectively fixed and improvised segments: tensions begin to mount leading to discharges; relationships develop from contacts which then lead to consensus or dissent.
