Laurie Spiegel - East River Dawn (Extended)

I may have over-extended it, but whatever... this is one of my favourite pieces of electronic music and has been ever since it was released on the 2012 expanded edition of the 1980 album "The Expanding Universe". The original version of this is 14 minutes long. Recorded sometime between 1974 and 1977.
