The technique of cutting a closed circular groove into a record so a short phrase repeats endlessly until the needle is lifted by hand · the gesture carried by the physical object rather than the recording, and the record made to refuse to end.

A lock-groove (or locked groove) is a groove cut into a record as a perfect closed circle rather than as the usual inward spiral. When the needle reaches it, it cannot move on: it repeats the same fraction of a second of sound over and over, forever, until a hand lifts it off. The technique is as old as the disc itself · the run-out at the end of any record is a kind of accidental locked groove · but used deliberately it becomes a gesture, a way of making the physical object, rather than the recording it carries, do the conceptual work.

The principle is refusal. A locked groove is a record that will not end, that demands the listener intervene, that turns playback from a passive act into one requiring a decision. This places the gesture squarely in the avant-garde and F·12 Fluxus tradition of the record as object and as event: the locked groove is a small conceptual machine, closer in spirit to a Fluxus event score than to a song, and its meaning lies in what it does to the act of listening rather than in the second of sound it contains.

The defining release in the genre's orbit is RRRecords' RRR-500 (1998): five hundred lock-grooves by five hundred artists, two hundred and fifty to a side, each a closed circle the listener must find and place the needle on by hand. It is, by reputation, one of the great record-as-object ideas: not an album to be played through but a field of tiny loops to be navigated, manually, one at a time, over what its owners describe as a near-endless span of listening. The contributors run from noise figures (Masonna, Aube, the Haters) to the larger experimental and rock world (Sonic Youth, Thurston Moore, Terry Riley, People Like Us), which is itself part of the gesture: five hundred artists reduced to equal one-second citizens of a single object.

RRR-500 was the successor to RRR-100, an earlier 7" that gathered a hundred artists in the same way and proved successful enough to scale up fivefold. Both came from RRRecords, the Lowell, Massachusetts label and shop run by Ron Lessard (who performs as Emil Beaulieau, and whose own live work uses a custom multi-armed turntable to play several grooves at once). The lock-groove compilations sit alongside RRRecords' founding role in American noise · the label issued the first American vinyl by Merzbow, Masonna and others · as the most-cited examples of the technique put to compilation use.

The lock-groove has a conceptual cousin in the run-out etching: the message scratched into the dead wax at the end of a side, which a listener finds only by inspecting the object. The runout etchings on the Runzelstirn & Gurgelstøck Asshole / Snail Dilemma LP ("YOU THINK THIS IS A JOKE?" / "CHURCH OF RUDOLF") are an example of the same impulse: the record as a physical object that carries meaning in places the playback never reaches. Both the lock-groove and the etching insist that the vinyl artefact is part of the work.

The technique's position in 2026 is that of a standard noise-and-experimental gesture, kept alive by the vinyl format itself: a lock-groove can only exist on a physical record, and the gesture is therefore tied to the survival of the format. The digital reissues of lock-groove compilations are necessarily compromises · a loop played a fixed number of times in sequence is not the same as a circle the listener must navigate by hand · and the Bureau notes that the technique is one of the clearest cases in the archive where the physical object is not a carrier of the work but the work itself.

The Bureau holds the lock-groove as a record-as-object technique, filed under Fluxus for its conceptual lineage. The closed-groove mechanism is the method; the Fluxus tradition of the record as event is the principle; RRRecords' RRR-500 is the defining release. The file documents the record made to refuse to end.

Coda.

Lock-grooves are filed in the Techniques subsection because the closed groove is one of the clearest cases in the archive where the physical object is not a carrier of the work but the work itself. The closed-groove mechanism, the Fluxus tradition of the record as event and RRRecords' RRR-500 together constitute the documentation the file collects.

The Bureau notes the position plainly: the lock-groove can only exist on physical vinyl, so the gesture is tied to the survival of the format, and its digital reissues are necessarily compromises. The record is made to refuse to end, and the listener must decide when it does.
