"Countryman Phase Shifter"

The fabulous Countryman Model 968 Phase Shifter. Manufactured c. 1974, this circuit was the heart of my feedback piece Pea Soup. This specific box, which I bought on eBay in 2005 in a fit of nostalgia, had been owned by the legendary "Different Fur" recording studios in San Francisco.

"Nicolas Collins: About Pea Soup"

I composed Pea Soup while a student at Wesleyan University. A self-stabilizing network of analog circuitry (originally three Countryman Phase Shifters) nudges the pitch of audio feedback to a different resonant frequency every time the feedback starts to build. The familiar shriek is replaced with unstable patterns of hollow tones, a site-specific raga reflecting the acoustical personality of the room. These architectural melodies can be influenced by moving in the space, making other sounds, or even by letting in a draft of cold air. The piece existed both as an installation, responding to visitors, and in a concert version, in which people performed activities intended to influence the feedback.

In the late 1990s I tried to replicate the now unavailable Countrymen, and by 2002 developed a fair emulation in software, which I return to for minor tweaks on a regular basis. Thirty years on I began touring the piece again, and re-positioning what was a typical 1970s task-oriented work of strict Minimalism with a freer occasion for "improvising with architecture."
