Released October 1968. Ten Bach pieces, each recorded note-by-note on an eight-track machine because the Moog modular was monophonic. Roughly 1,100 working hours of overdubbing. Carlos and Benjamin Folkman played the parts; Rachel Elkind produced from the West 88th Street brownstone studio she shared with Carlos.

The album reached Billboard 200 #10, topped the Classical chart from 1969 to 1972, sold a million by 1974, went platinum in 1986. Three Grammys. Robert Moog's sales department was overwhelmed within months. The original 1968 sleeve (model in Bach costume seated at a Moog whose headphones were plugged into the wrong jack) was quickly replaced with a standing version after Carlos and Elkind complained. The Third Brandenburg track, which Moog played at the 1968 AES conference, is the moment the engineering establishment realised the instrument was no longer experimental.
