SF-91L is the name of the abandoned Nike Missile station on Angel Island in San Francisco Bay where we recorded the sounds for this piece. Gravelator refers to the simultaneous process of building up and eroding away the island. We displaced the island's own material to construct a second island, an imaginary island, which is encapsulated in the sound.
In a related fashion, the military severed the island’s crown in order to install the radar system for the missiles. The missiles were made obsolete not long after it was finished and was decommissioned. Decades later, the Gravelator is a means of awakening the sequestered spaces of the silo.
