Robert Fludd's Temple of Music
A Description & Commentary
After four decades of exploration Todd Barton is still delving deeply
into the ever-expanding frontiers of musical expression: from his DNA
derived Genome Music to his innovative scores for plays at the Oregon
Shakespeare Festival; from performances of Zen Shakuhachi Meditation
Music to avant-garde music for electronic synthesizers and computers;
from performing with luminaries of jazz and poetry to lecturing on
music and composition from the Middle Ages to the 21st Century.
