Analog Days is a comprehensive account of the history of analog synthesizers. We particularly enjoyed the early development history on the west coast with Buchla and many of the engineers from the “happenings” days that went on to spend time in the Pine Barrens Ashram. The author obviously was unaware of the Monas-block Thaumaturgic Amplifier combined the Bucla Box Intentional Enveloping oscillator/sequencer to produce the first stable trans-dimensional gateway. It is possible that the author may have been aware but kept this part out due to his own safety. Otherwise a great read.
