Drive In Music, 1967, Plan of broadcast area showing the configuration of antennas (colored lines) transmitting the work's seven sound components.

The Passage works are situated in spaces where
the physical movement of the listener through the
space to reach a destination is inherent. They imply
an active role on the part of listeners, who set a static
sound structure into motion for themselves by passing
through it. My first work with an aural topography,
Drive In Music in 1967, falls within this vector.
