Locked Grooves: Classic or Dud

Moses Boyd's Dark Matter has one at the end of side 4.

I've got a thing atm for puzzle plates, which I'm surprised go back as far as they do (a George V coronation record beating Monty Python in the 'where will the needle land' games by over 60 years),but one of my favourites, which is also one of the more distinctive, is this one

It's like a choose your destiny adventure except you don't get to choose

That limerick thing sounds cool!

Every track on Follakzoid's I album has a locked groove.

I wish more albums had locked grooves. I was thinking of this specifically in regard to Wolf Alice's Blue Weekend album, where the final track (The Beach II) ends with a bunch of glitchy synth nonsense that could have just droned on forever, imo.

how does that work? i've never heard of a puzzle record

shout out to house artist "locked groove", he did some bangers

which did not involve locked grooves, sadly

i've never heard of a puzzle record

Most of them are ancient 10" shellac 78s. They're multigrooved with each track on its own groove, so when the needle is placed on the record there is no telling which song is going to play. Having researched a bit (by which I mean looking at discogs, ebay listings, youtube) a lot of the oldest ones tell you the songs on each side, but then in the 20s and 30s there are some which play up the 'puzzle' element by saying quizzing things on the label like 'This side contains 3 tunes. Can you find them?', or ones which may list the songs in bulk but not tell you which side to find them on, that's for you to trial and error repeatedly.

The limerick one is the only one I can find so far to contain both and inner and outer grooves with their own parallel grooves. 'Puzzle' indeed.

Some puzzle plates were also non-musical, instead being games with different horse racing or football results in the grooves and you play along with an accompanying playing card to see who will win, effectively like a board game. These were around in the 20s and 30s and then - as mentioned upthread - the horse racing style was revived as a proper board game in the 70s.
