After a few years busy with various collaborative music projects (and non-music projects), I sat down to make an album. Within a couple of months, I had enough material for three. This was part one of an intended trilogy. Part two is the 'Tapes' record, part three is sitting on a shelf for now.

"Figure 17 - A research volunteer at NYU learns to relax by listening to the clicks she hears in the earphones every time her forehead muscle contracts. When this happens, it generates a very small electric voltage which is sensed by the metal contacts seen attached to the subject's forehead. These voltages are fed into a special amplifier which filters out those signals which are irrelevant and then multiplies the muscle voltages enough to create a clicking sound in the earphones. In that way the subject hears even the most insignificant changes in her muscle tension."
