Ruggle's "Sun-treader"

Carl Ruggles, one of the most original voices in 20^th century American music, was a curmudgeonly man whose musical output totals just ten works, which he endlessly re-wrote and edited as close to perfection as he could.  His works, including Sun-treader, exhibit a freely evolving nontonal polyphony, through which he expressed his wish for freedom from the past.
