(Jim Pallas Plays For Barbara Levin.  1973)
In 1961, a young Detroit attorney,  back home from Harvard, and his wife, bought my intaglio print, "ZIP", out of a student show at Wayne State University.

A few years later, I showed some sculpture in his office for a fund raiser.  The attorney was Carl Levin who represented  indigents in criminal cases at the Michigan Defender’s Office.  We stayed in touch.  He and his wife, Barbara were interested in buying a sculpture but didn't have much money.  By the time he saved up enough to meet the price I last gave for something, the price had gone up.
During this time I was finishing the Wheel and Pendulum series and wanted to make an artwork that would be affected by  a factor outside of itself.
In their living room was a harpsichord that Barbara had built from a kit.
 I asked her to play something for me.  So she sat down and ripped off a little Bach number from memory.   She said she would like a sculpture to go on the wall over her harpsichord. I said I would like to make a sculpture respond to the sounds of the instrument and express some of the qualities of those sounds in its form.  They liked the idea.

  I enlisted the aid of a self-taught engineer who was working for Stanford Ovshinsky at Energy Conversion Devices.
 (Quite coincidentally, Barbara worked at Energy Conversion Devices many years later.)

The amazing Dick Dudchik, a meticulous designer, photographer and pilot, created the circuitry for J.P.P.F.B.L.which counted audio events in the three frequency ranges.  He introduced me to the then new TTL family of integrated
 logic circuits.  Later he designed circuitry I used in several sculpture in the early 1970's.  They served as models for circuitry I developed later including another commission for the Levins.
