I think it all depends on where you define your different epochs of rock to occur.
I believe the first would start with Jackie Brenston’s “Rocket 88”, go through Bill Haley and the Comets, Doo-Wop, The Platters, Elvis, Chuck Berry, Buddy Holly, etc. and end with Elvis’ induction into the army, although there may be a slight bleed-over to the death of Buddy Holly.
With Elvis safely ensconced in Germany, the “Teen Idol” era began: Pat Boone, Ricky Nelson, Paul Anka, Bobby Darin, Bobby Vee, Bobby Curtola, Fabian, Cliff Richard, etc. All very white, very homogenized and totally non threatening; rock had been, to an extent, vasectomized, and this couldn’t even be ended by Elvis’ return, or the dawn of surf rock with the less-than-mainstream Dick Dale or the more-or-less “as heard on AM” Beach Boys. In fact, this period wouldn’t really end until November 22, 1963 and the assassination of JFK, although there had been some degree of change in the air, although not in the US: The Beatles released “She Loves You” in late August 1963. According to Wikipedia: “It entered the charts on 31 August and remained in the charts for thirty-one consecutive weeks, eighteen of those weeks in the top three. During that period, it claimed the ranking of number one on 14 September, stayed number one for four weeks, dropped back to the top three, then regained the top spot for two weeks starting on 30 November. It made its way back into the charts for two weeks on 11 April 1964, peaking at forty-two.” Although “I Want to Hold Your Hand” is the song most often associated with the dawn of Beatlemania, “She Loves You” predates it by four months."
Thus began the next phase, “The British Invasion”, which properly lasted in the US from February 1964 (when The Beatles appeared on Ed Sullivan) until approximately fall of 1966 when US acts were finally able to start charting with some degree of success again. There actually were two waves of the British Invasion, the original one in 1964, and a second smaller one in 1965, when more UK acts started to tour North America. “The British Invasion” can also correctly be said to also be the start of the 1960s, in musical terms.
The period from the fall of 1966 to approximately the breakup of The Beatles in 1970 is one where anything seemed to work. There really were no particular trends during this period that are really discernable.
Post the breakup of the Beatles, there was a small period where most hits were made by members of the “Singer/Songwriter” trend; concurrent to which was the infancy of acid rock/heavy metal with rise of Jimi Hendrix and the metamorphasis of The Yardbirds into The New Yardbirds into Led Zeppelin. Parts of this trend would later evolve into the “Arena Rock”/“Stadium Rock” phase of the mid-70s, in which bands like Zeppelin and Black Sabbath would be joined by the Top-40 guild which was also packing them into those types of venues, such as The Eagles, Fleetwood Mac, Peter Frampton, etc.
Disenchantment with millionaire rock stars and the trappings of fame would result in the rise of Punk Rock, which would run out of venom and evolve into New Wave, effectively ending the 70s.
