Curious record side labeling


Do any of the jazz gurus on here know why some double-set records have this curious side labeling where record 1 has sides A and D, and record 2 sides B and C? It does not make much sense to me, and I wonder what purpose it serves other than to confuse the listener. I noticed this with a couple of Coltrane records from the '60s, recently with "The Other Village Vanguard Tapes."

I remember my parents had a record changer in their console that had a device with a claw like clamp that would flip the record over (78 rpm). If memory serves me right it was a Stanton. Now that was progress , early 1950's.
No doubt vinyl today is valued for its sound quality and most things revolve around that. Well, maybe album art and some enjoy physically interacting more with their recordings than digital usually permits.

But from the 50-70's, when vinyl and apparently also changers were king, it was more about musical selection and convenience. That's what most people played records for. Audiophile type users were a very small minority.

Neat how times change.....
When the LP came out, it was a quantum leap in so many ways over the 78--way better sound, it held far more music, and was far more durable as well. It never occurred to most people that the LP was capable of far better sound than they were hearing, and many wouldn't have given up the convenience anyway. The audiophiles who went for better sound with more expensive cartridges, careful handling, and single-play manual turntables were definitely on the fringe.

Until the '80s changers still outnumbered single-play 'tables.

I have a couple copies of the Capitol Beatles 2-LP compilation titled "Love Songs." One is pressed and numbered for a changer (1&4, 2&3) and the other is for single play (1&2, 3&4).
Does anyone know if the side sequencing has been changed with recent repressing.
I'm listening to Tommy and hate the 1-4, 2-3 sequencing. I would definitely purchase some Lp's again to get it right.

Yes it is available in the sequencing that you want. Keep the version that you have though, it is an original pressing. Here is a link to purchase.

I did get a little laugh reading this discussion. Man what would people here have done with the original pressing of WoodStock, it's sequencing of album sides was 1-6, 2-5, 3-4. When that was first released we all thought how great it was. Stack the 3 records on the changer, listen to 3 sides then flip and listen to the other 3 sides. An engineering marvel !
