Silbury Airis named after Silbury Hill, a prehistoric mound in Wiltshire, the biggest artificial mound in Europe, being 125 feet high and covering more than five acres. Its use and purpose, after centuries of speculation, still remain a mystery. The music of theAiris not in any way meant to be a romantic reflection of the hill’s enigmatic location nor a parallel with any of its evident geometry. Seen from a distance the hill presents itself as an artificial but organic intruder on the landscape. I have often alluded to my music of landscape presenting musical ideas through the juxtaposition and repetition of static blocks of, preferable for my terminology, objects. These objects themselves being subjected to a vigorous invented logic via modes of juxtaposition, modes of repetition, modes of change. The sum total of these processes is a compound artificial landscape or imaginary landscape, to use Paul Klee’s title.
