Expectedly — and with afterthought, not a surprise — a phone conversation with sound sculpture artist Bill Fontana is textured with sonic anomalies. “Ping, ping,” warns his Nissan Leaf before San Francisco-based Fontana announces, like a narrator, “I’m driving an electric car. It only makes a sound when it’s backing up.”

Later, the phone’s “whoosh, whoosh” while on hold during a call from his 17-year-old daughter establishes that silence is not quiet. A Bluetooth bloats the vowels in Fontana’s words, lending a sonorous, luxurious underwater effect. Syncopated accents arrive with a car-door slam, unexplained rhythmic ticking, traffic noises.
