Locked Grooves Vinyl – Endless Fun (Literally)

Marc HenshallCulture & Industry31 Comments

In a recent feature, we explored the weird and wonderful world of run-out groove messages. From mastering engineer signatures to hidden messages and inside-jokes, there is a whole world of interesting etchings to explore. Closely related to this topic is the world of audible locked grooves.

Standard records have a locked groove at the end of each side, usually in the form of a silent loop that keeps the stylus from drifting onto the label. It is possible to incorporate sound into this extra space, and many artists and engineers have used the technique over the years to create infinite loops. Locked grooves are a perfect example of how the vinyl format is more than just a medium for storing music; making records is an art form in its own right—a white canvas for creative expression.

There are countless great examples of locked grooves in action, here are some of my favorites:

The Beatles – Sgt Pepper

Perhaps one of the most well-known examples of a locked groove is The Beatles’ Sgt. Pepper’s Lonely Hearts Club Band. After the last track, the deadwax reveals a creepy layered loop of voices that plays to infinite. The band were fascinated with tape manipulation and Musique Concrète, a musical style often touted as pioneering the world of electronic music.

The band’s obsession with early avant-garde electronic music is also evident from the front cover of Sgt. Peppers, where if you look closely, there is a picture of Karlheinz Stockhausen, a German avant-garde electronic composer. Interestingly, even if you could decipher the hidden words in this seemingly LSD-fueled loop, there are countless different examples from one pressing to the next.

Check out the YouTube clips below and you’ll hear the most common loop closely followed by multiple other examples from different releases.

Pink Floyd – Atom Heart Mother

The last track on Atom Heart Mother is a curious part-soundscape, part dialogue affair, featuring the bands then roadie, Alan Styles preparing, discussing, and eating breakfast.

If that wasn’t mad enough for you, the piece came about by Roger Waters experimenting with the rhythm of a dripping tap. The original LP opens and closes to the sound of a tap, which continues into the locked inner groove. If left unattended, the drip plays on indefinitely.

Jack White – Lazaretto

Most records play from the outer edge in, but not in the case of Jack White’s Lazaretto “Ultra LP”. In this instance, side A plays from the inside out.

At the end of the side, there is an unconventional locked groove on the outer edge—something of a first in vinyl record production (as far as I know). Side B also features a locked groove, albeit in the more conventional sense.

The Mars Volta – Frances The Mute

Here’s one that for some folks is a bit of a Holy Grail. Released in 2005 (back before the vinyl revival really took off) the limited-run vinyl pressing of Frances The Mute, by The Mars Volta has locked grooves on all three records.

The really clever thing is, when you get to side two, the beginning of this side starts with the exact same loop as the locked groove on side one. This continuation effect lends itself perfectly to the modern progressive rock aesthetic of The Mars Volta; here’s an example of side one in action:

Rush – Fly By Night

If you’ve discovered Rush later in life or as a young person after the time, you’ll likely be familiar with how the chimes at the end of “By-Tor and the Snow Dog” fade-out over time. Pick up a 1970s copy, however, and you’ll be treated to never-ending chimes, as they loop indefinitely into a prog-rock abyss.

The Moody Blues – On The Threshold of a Dream

I’m a huge fan of albums that start and conclude with the same riff, motif, or atmosphere. To me, they always feel like a well-written paragraph—elegantly constructed and beautifully planned. The Moody Blues are pioneers of the perfectly composed prog-rock album, so their style naturally lends itself to the creative use of a locked groove. Check out the end of side two, where the same analog synth sound from the opening track continues into a loop. Later CD and tape editions of the album simply fade-out slowly.

Locked Grooves Vinyl & The Art of Making Records

I could go on. You could include the cult album “Unknown Pleasures” by Joy Division as another example, which also ends with a locked groove playing the sound of breaking glass repeatedly until the tonearm is lifted.

There are countless other examples, and I encourage you to share your favorite locked groove examples in the comments below.

Arguably, no other musical format leaves so much to the creative imagination in realizing an exciting and collectible product.

What strikes me most is how the novelty hasn’t worn off; yes, a lot of examples are from the 60s and early 70s when psychedelia was at its peak, but there are plenty of contemporary examples to match.

That’s the beauty of making vinyl records; there is always another angle and a new way to use old techniques to express the artist’s creativity. Vinyl is the ultimate physical format.

Mordecai Smyth’s Lp, “It’s Getting Stranger On The Shore”, from 2022 has a locked inner groove on side 2.

Three to offer here: The British copy of Eno’s Taking Tiger Mountain has those crickets chirping endlessly! Lol.
Second, Monty Python’s Matching Tie and Handkerchief has three sides! Side “two” has parallel grooves so whichever one the needle drops on it plays those tracks!
Third: Aphex Twin’s Analog Bubble bath Vol. 3 has two on the same side! a locked groove in the middle of the record with no sound. You have to pick the needle up to play the final track which then ends with, you guessed it, another closed groove – this time with a sound. 😀


On abba’s super trouper the crowd noise at the end loops infinitely on copies not from the usa


Punish records release 10.5
Techno record

weirdest runout i have is jedi knights “May the funk be with you”, the groove dances all over the surface of the entire vinyl, long runout style grooves in the middle of the album, not for linear tracking tt’s for sure!

When I was in grade school, many years ago, we had choral records that had 7 or 8 songs per side. And each song ended with a locked groove, so we could practice, hearing only the song we intended.

Scott G

Feedbacker by Boris. Locked groove both sides.

Lou Martin

The first album by James Gang, ‘Yer Album’.
In the locked groove on side one you will hear “turn me over” and on side two “play me again”.
Some other Joe Walsh albums have words etched into the blank space of the vinyl where the groove runs to the locked groove. E.g. ‘But Seriously, Folks…’; side one – what can you do for a dog with no legs?
side two – take him for a drag

T Clark

mine says “Luncheon counter of the deli kind” and “call it in the air”

Jeff Pike

On the debut album from the funk rock Atlanta band, Mothers Finest, there are two very short messages at the end of side one and side two. Side one says “Turn Me Up.” Side two says “Louder, Louder.”


At the end of Def Leppard’s High n Dry, the song No, No, No has them yelling the song title in a infinite loop. I always loved this one!

Paul C

I have 3 Sgt Pepper Lp’s and and 4 turntables and only 1 plays 2 seconds of it before going home the rest just go home. , I guess you need a special Player for these? I wonder if there is a way to fix it? so it play’s it ?

Andy Unger

Buzzcocks – Another Music in a Different Kitchen. The notes keep escalating in a pataphysical scale after the end of Moving Away From The Pulsebeat on Side 2. (It has it’s own title, not mentioned on the sleeve “The End”) And, as far I know, this is only on original UK pressings. The more recent reissues fade out.

John Wyant

Also, Peter Gabriel’s 2nd solo album, sometimes referred to as “Scratch”, end of side 1 – “White Shadow” ends on a single note that continues for ever.

John Wyant

2nd side of Rick Wakeman’s “Six Wives of Henry VIII” – “Catherine Parr” ends with a huge crescendo on a rising note – which ends in a single high pitch which continues into the runout groove.


A few others:
The end of The Muppet Show 2 album which has Fozzie accidentally locked inside the theatre after everyone else has gone and calling out “Help” repeatedly in the locked groove.

The end of Side 1 of “Initial Success” by BA Robertson which has a telephone voice saying something like ‘Sandy Nelson first entered the charts in 1959 with….let there be drums’, these words being repeated in the locked groove.

The end of Side 1 of “You and me both” by Yazoo which has one of the band members say “I think you should do the first one again Vince” which is followed by the sound of laughter which repeats in the locked groove.

The end of Side 1 of “Another Monty Python Record” which ends with someone saying “Sorry Squire, I scratched the record” repeatedly which eventually goes into the locked groove.


I checked out my copy of “Initial Success” but sadly it just ends with the voice saying… “Let There Be Drums..” There is no locked groove. Maybe because I have got the German pressing of the record or something.


Just picked up a copy of Initial Success. it’s the last track on side two that has all the fun, I believe it’s a double-groove? Depending on where te stylus drops it will play one of two versions, one telling you that the needle “is going to sliiiiiiiideee” onto the label, which it duly does.
I tried it again, and it was a completely different ending.

Bit late to the party but I was just playing the Super Trouper Vinyl and started browsing on the subject. I have two more:
We’re Going to Live for a Very Long Time by Heaven 17 (Penthouse & Pavement) for a Very Long Time for a Very Long Time for a Very Long Time for a Very Long Time etc
I Am The Beat by The Look (7″inch, repeats Beat, Beat, Beat, Beat)

Steven Shears

Jeff Mills – Cycle 30 which has 8 loops which act as techno tracks! IH


The Cowboy Song by Public Image Ltd… it was the B-side to the song Public Image, 45 RPM on Virgin Records…


the vinyl abba super trouper records have an endless applause on side B.


not on us copies

Anders H

“Go Insane” by Lindsey Buckingham is another example.


Side two of original ZZ Top Eliminator… “Oh Mercy!”

Marc, thank you for the plug and for taking my once meager idea of a blog to astonishing new heights. Very well-written and fun indeed, with great examples galore. I would add (for the uninitiated) that these locked grooves will only be heard on a manual turntable. Any turntable with an auto shut-off feature will only play the locked groove information for a fraction of a second before the turntable’s automation kicks in. Hope some of the readers will contribute as there’s bound to be many, many more. Cheers and wellness from the Bay Area.
