In this music I have dealt with space and sound as attributes of moving images in time. The alto flute provides the timbral material for the electronics consisting of multiphonics and harmonics, whilst the piano 'colours in' the flute's timbral variations with short motives deriving from the flute's melodies. As in a moving universe, both instruments are projected onto dissimilar spaces delineated by the spectral content of the flute.

Afterglow is the third work of a triptych based on piano and a woodwind instrument where I have explored each duo in terms of spatial and timbral relations. The triptych consists of nowhere (clarinet, piano and electronics), from the lake (oboe and amplified piano) and afterglow (alto flute, piano and electronics). As in the other two works, in afterglow my perception of space was inspired by a short poem using minimal syntax and condensed imagery.

Afterglow was commissioned by and written for Arianna Palin and Detta Danford. The premiere took place at The Space, in London, during the Enterprise Festival on 23rd June 2006. The performers were Detta Danford (flute), Arianna Palin (piano) and John Palmer (electronics).
