**Invitation to Listen in a Van (for Wendy Carlos) (2019) **is a** **tribute in the form of a social sculpture—with a clunker van, discography in “road case,” digital “mixtape,” blinking neon roof beacon, hi-fi sound system with subwoofer, screen print (ed. 50), and snack kit. The small *i*: "It represents the mathematical term for the imaginary number constant, defined as the square root of minus one, a concept that doesn't exist in the real world, but helps solve many equations...Math and physics people routinely refer to small *i*, the imaginary number. I must have picked that up from my days as a student at Brown University, when I shifted my focus, first in physics, and then in music and composition...The tiny *i* is located at the base of the transistor schematic, as this is the normal input for this minimal circuit component. It's all terribly clever, don't you see, that Tempi's music-notehead is a transistor, the main element of a Moog synthesizer, and it's located to amplify (are you ready?) imagination, symbolized by the imaginary number, *i*."
