From the rail yards of Wisconsin
The voice beneath the rails
Built to find flaws in steel. Destined to find them in us. The OnePass is the world’s first ultrasonic rail‑testing theremin — an instrument played without touch, tuned by ten thousand miles of track, and heard, in its purest register, only by dogs.
Specification sheet
For years, the OnePass rolled the mainlines of America doing honest work: flooding rail steel with ultrasound and listening for the flaws that answer back. Transverse defects. Shells. Seams. It heard them all, and it told no one but the report.
Then somebody plugged it into an amplifier.
Like the theremin, the OnePass is played entirely without touch — the operator’s hands never meet the steel. Unlike the theremin, it requires forty feet of clear track, a certified flagman, and the patience of a freight schedule. Purists insist this is the point.
No strings. No keys. No contact. The hand hovers; the wheel decides.
Every note begins above 20,000 Hz. Audiences describe the encore as a feeling in the fillings.
No retakes. No overdubs. The name is a promise and a threat.
Where lesser instruments sweat, the OnePass glistens. Ask about our gel.

Operator. Composer. Flagman of the avant‑garde.

Eleven years walking Midwest mainlines as a certified flaw‑detector operator. Ten thousand miles of steel. Then, one October night outside La Crosse, a defect echo came back in D minor — and Joe Kingston stopped testing the rail and started listening to it.
Critics have called his sound “unprecedented,” “unclassifiable,” and “technically a reportable incident.” Joe calls it the truth. His debut long‑player, Ultrasonic Meditations, Vol. I, was recorded live in a single pass between mileposts 281 and 296, because that is the only way he knows.
“I don’t play the OnePass. The rail plays both of us.”

Timetable no. 3 — subject to change without whistle
Every venue within thirty feet of active track. Ear protection discouraged — it makes no difference.
LOADING THE BOARD…
Dates leave the board the moment they pass. The OnePass does not look back.
The company store
Heavyweight cotton in signal black. Hazard stripes at the hem, milepost numerals down the spine.
180-gram vinyl. Forty minutes, one pass, zero edits. Side B is silent to the untrained ear.
The very gel that carries the note from wheel to rail. Limited “Encore” scent. Not for consumption.
Pulled from decommissioned track and signed by Joe himself. Each one slightly different, like the flaws.
