Drew Mulholland performs "Lux Occulta" by playing the Harp in a gesture based manner, tracing the score of symbols above.
"The inspiration for 'Lux Occulta' came
from the alchemical symbols for
different aspects of Light such as sunlight,
moonlight, reflection and refraction, as used by both Cornelius Agrippa's
(1486-1535) "Three Books of Occult Philosophy or Magick",
and Elizabethan mathematician, alchemist,
philosopher, and occultist "Dr. John Dee (1527-1609).
I wanted to return to the first principles of researching,
and these strange almost mystical glyphs were ideal for the
composition, as they no more resemble a traditional score
than the Halo Harp resembles a traditional instrument."
