1964 was the great year of the music convergence..The British Invasion hit the states, Motown took off, the California surf sound hit its peak, the girl groups, even Lorne Greene had a hit. Why did it occur in 1964 instead of a year later (or earlier)?
I would highly recommend reading Bruce Spivey's books for a little history on why it took until 1964 for the Beatles to conquer the United States. Seems that Capitol's A&R guy at the time hated the Beatles and did everything in his power to prevent them from breaking through in the states in 1963. But eventually the buzz over the Beatles got so loud that the president of Capitol asked to hear something by them. And he overruled the A&R guy, and released "I Want To Hold Your Hand" on Capitol. The rest is history.
I would say, however, that the girl group sound was actually nearing its end in 1964, save for the Supremes, who probably had a hand (at least indirectly) in killing off all the "lesser" girl groups of the earlier '60s. And the surf sound had been going for several years by then, and still had a year or two left to go.
Why 1964? A better question would be why
not 1964?
