expost: Charles Giuliano wrote a piece for something called the Broadside/Free Press centering somewhat on Joe McCord's mime act, and describing the Dead's performance without any song specificity. It's a good piece that captures some backstage color. Pigpen: "Karlheinz Stockhausen says that in music there is only invention or boredom." Garcia is invoking literature, French avant-garde film and Nietszche's philosophical godfather, Schopenhauer.
A 1.2 megaton thermonuclear device is tested at Amchitka Island, Alaska. This test is code-named Project Milrow, the 11th test of the Operation Mandrel 1969-1970 underground nuclear test series. This test is known as a "calibration shot" to test if the island is fit for larger underground nuclear detonations.
