The Beatles vs. The Rolling Stones


If you had to choose that one of these groups never existed,which means that all their contributions to popular music never happened which one would it be?

In the context of your question, the Beatles are more important, for several reasons.

First, the Beatles had George Martin as a producer. He literally created production techniques that had never been tried, and set the standard for the multi-tracking and invented studio techniques and tricks later to be expanded upon by many big name groups in the late 1960's and early 1970's.

Second, the Beatles had Brian Epstein as a manager. He recognized their raw talent, groomed them through the dumpy clubs in Hamburg and Liverpool, and got them ready for "game-day"...their 1964 American tour. I also believe that he was the one who replaced Pete Best with Ringo.

Third, the Beatles were "nice boys"...charming, humorous, witty, and not "scary looking". Even in their early days, the Stones were pretty rough looking. The Beatles were more marketable than the Stones. After Elvis was inducted into the Army, the "Payola" scandal, the persecution of Alan Freed, and the religious backlash in which R&R music was either the work of Satan, or "N..ger music" to seduce and ruin the chastity of young white woman, by 1963 there was no true R&R on the American airwaves [other than small market stations]. It took a likable, non-threatening group to revive R&R. The Beatles opened the "British Invasion" floodgates.

Fourth Beatles had a legendary song-writing duo [Lennon-McCartney]. I think that their competitiveness, and different styles resulted in a tension that made the sum of their songs greater than the parts. Lyrically, the Stones weren't even close to the depth and range of material that the Beatles wrote.

Fifth, as alluded to before, the Beatles set the standard; everyone else tried to follow. Remember the sitar craze after the Beatles went to India? Short lived [thank God!] as it was, dozens of artists had to include a sitar on one of the album songs [if you hear a sitar on a R&R album it was recorded in either 1966 or 1967]. Remember the production competition between the Beatles and the Beach Boys [Brian Wilson]? "REVOLVER" followed by "PET SOUNDS" followed by "SGT. PEPPERS". I have heard that a bunch of prominent musicians [including Brian] got together to hear a pre-release tape of "SGT. PEPPERS...they listened so many times that the tape actually wore out! Someone in the group of listeners glumly proclaimed, "Now what do we do?!!!"

The Beatles were originally a R&R/blues band that transformed into what I classify as an "Art" band. The Stones have stayed a R&R/Blues band. I like both groups, but the Beatles definitely had more influence on the acceptance and evolution of R&R music, and studio production.
Fatparrot said it all; I'll take the Beatles, you can have the stones.
Until the Beatles, no one ever did anything like Eleanor Rigby, Nowhere Man, or Within You Without you.
I agree 110% with Fatparrot - the Beatles were simply the most creative group and injected R&R with so much more than the Stones who were/are a great R&R band.

I must add the Yardbirds were easily the most tecnically competent group - incredible music that opened the door for more experimentation.
