Rock didn't invent the 2-4 "money beat" It's a lot older than the 60's lol.
Any thoughts on when/what some of the first uses of it would be, in American popular music? Assuming we're talking straight, and not swung, and with drums? It's something I've often wondered about. (In other words, meaning, yes, played on something like a modern drum kit, which is only about a century old.)
The earliest Elvis Presley, Chuck Berry, Little Richard and Buddy Holly songs (that I can think of) all had that swung feel, although sometimes they'd have that sort of half-swung/half-straight groove, such as 1957's "Jailhouse Rock." Little Richard's "Lucille," also from 1957, is one of the first (again, that I can think, and I'm not claiming to be an expert, by any means) to have a truly straight feel. Some of the others which have a straight feel—"Peggy Sue" and "Everyday," for instance—don't have the money beat. A few slightly later Holly tunes — "It's So Easy" and "Maybe Baby"—sorta do. (Is playing the snare on 2& still the money beat?) And while obviously 1958 is indeed before the 60s, it's not all that much before it.
I'm assuming there are many instances of jazz or blues recordings from the 30s or 40s which would fit the bill, but I can't think of any off the top of my head. If someone knows of a study on this topic—I'm sure there've been many—I'd love to be pointed in the right direction.
ETA: and of course minutes later, YouTube recommends this video to me.
