Vinyl: Locked Groove

By soulchap
updated 2 months ago

All vinyl records (at least as far as I know) end in a locked groove - this is done to protect the stylus from drifting onto the label, etc. A locked groove simply never advances; the groove changes from the spiral it was on the way in to a closed circle. Many of us have experienced the heartbreak of a home-made locked groove, a.k.a. a "broken record," that repeats a phrase ad infinitum until one gets off the couch and picks up the tone arm and manually advances the needle.

Along the way, someone figured out that the "runout groove" was arable land waiting to be seized.

Why, then, would anyone do this on purpose? One finds albums of locked grooves in the Library Music world; discs of sound effects were manufactured for the purpose of providing the sound of a continually dripping faucet, say, for a radio drama, etc. DJs building dance tracks live, on the fly, in clubs or while recording, found that infinitely looping snippets were useful and worth stockpiling. There are examples of "blank" locked grooves used within albums to separate tracks solely for the purpose of forcing the listener to advance the tone arm. Others were more playful.

I think that the recorded locked groove came, at some point, to represent the medium itself, a synechdoche for the phenomenon of vinyl recordings; one need only hear the reference to this experience on the Monty Python track which ends with the loop, "Sorry Squire, I scratched the record. Sorry Squire, I scratched the record. Sorry Squire, I scratched the record..."

I would like to break this list into (at least) two lists, one for workaday locked grooves, such as dj breaks and sound effects, and another for "easter egg" locked grooves, i.e., those meant to be found by chance, and those meant to extend the lead-in track into infinity. Someday.

    One of the best-known (and possibly the first) examples of this technique was The Beatles' Sgt. Pepper's Lonely Hearts Club Band (1967). Many UK copies featured a multi-layered collage of randomized chatter in their run-off loops. However, two variations were made: the original British pressing (black label with gold logo) has the "inner groove" play through the entire locked groove and does not include the laughter at the beginning of the piece. The re-issue of the British pressing (black label with silver logo) starts playing the "inner groove" long before the needle reaches the locked groove, includes the laughter and, once the needle hits the locked groove, the listener only hears the last two seconds of the piece played over and over again."
