This is for people who are still into vinyl. Here’s the question: what was the first record to have music on both sides?
For the answer, we must go back to 1904, just a few years after Emile Berliner introduced the idea of playing back music from a flat spinning disc.The first discs only had music on one side. But then a German label called Odeon came up with a marketing scheme: two songs for the price of one. Finish playing the record on one side, then flip it over and play another song.
Within a year, Odeon had 7,000 two-sided records for sale forcing all the other labels to ship records with an “A” side and a “B” side, although some companies held out with single-sided discs until the 1920s.
