SUZANNE CIANI SHOWING OFF HER SYNTHESIZERS AND FANCY GEAR IN DAVID LETTERMAN'S SHORT-LIVED DAYTIME SHOW, AUGUST 14 1980.

Ciani, an electronic sound effects wizard like no other, did the sound effects for Meco's disco version of the Star Wars music soundtrack in 1977. In the 1980's she began to record solo albums in the Private Music label. I still keep the Keyboard Magazine June 1979 issue that featured her on the cover.
