GridLeakBias said:I posted what should be self evident – major pop singers in the mid to late 50s gave up trying to copy the recently established rock ‘n’ roll sound, and went back to their pop ballad roots.
Lavern Baker recorded “Tweedle Dee” as an R&B novelty tune, it charted on R&B and Pop charts. The white cover version by Georgia Gibbs ranked as a pop tune.
“Four Walls” by Jim Reeves was a country ballad which also crossed over into the pop market.
The remainder of the tunes listed are pop ballads, not rock ‘n’ roll, even though a few of the artists mentioned, such as Brook Benton, later had recordings classified in the R&R genre. At best, tunes by Mathis and Boone would be pop oriented crossover soft rock.
To answer your question, no, I do not consider any of the above tunes to be rock 'n' roll. If you do, please note which ones and explain your reasoning. I'm easy.
You've explained your idea of the difference between pop and r&b. But you haven't given us your explaination of the difference between pop and rock & roll.
