All of the “Lost” 1976 Space Manufacturing Summer Study recordings have been cleaned up and are now waiting for you on the SSI Soundcloud Channel.
Plus there’s GKON on Good, Evil and all things in between,  and a little gem showing two professors practicing for what would, a few weeks later, become a legendary Space meeting.
The address of the Space Studies Institute Soundcloud Channel is:
