Now I listen to a lot of other groups nowadays, many which are you can call "underground" nowadays (King Crimson, Deep Purple, etc.)
I give you a lot of credit, Seafroggys; a guy your age getting into all that stuff is like a guy my age getting into Jelly Roll Morton, George Gershwin or Count Basie; something you don't see very often.
Though even calling Deep Purple and King Crimson "underground" kind of hints at the general narrowness of popular palate I'm referring to. I guarantee you that if you were around back in the 70s with the same open ears you have now, you wouldn't consider them even close to "underground". Hell, Deep Purple went Top40 a few times ("Hush", "Smoke on the Water", etc.) OK, King Crimson comes a bit closer, but I don't know very many people my age that aren't intimately familiar with both the cover and the contents of the "In The Court Of The Crimson King" album.
and many of them you can consider "better" on a technical level than The Beatles, but in all honesty....they were good.
Well, as I said, it was wrong for me to refer to them as "crap". I think that was more of a comment on my part to the legendary, mythological, superhero status that surrounded them then and now. Sure they were good, but they really were not - in the opinion of many who don't just parrot populist history - any better than a dozen other bands to come along at the time. I know, it's all a matter of personal taste, but for me, if I had to select just among the British invasion bands, I'd take the Animals and the Stones over the Beatles any day.
But the point remains that even the Beatles themselves would tell you (and have on many occasions in many ways) that the major "we're bigger than Jesus" legend-status hype around the Beatles that put them above the rest was never anything they ever actually earned, but rather was far more an artificial construct of the media than anything. Sure, they were a fine British rock band headed by a solid songwriting team and a couple of lead singers. So were a dozen other bands like them at the time.
And their older stuff is amazing...
In what way? No, I don't mean that sarcastically, that is an honest question. I really would like to know what it is you hear in "Love Me Do", "I Wanna Hold Your Hand" or "I Saw Her Standing There" that makes them stand above the rest, or wasn't already done with more energy and/or more soul by the jump bluesers and rock n rollers of the 50s?
As far as both Elvis and the Beatles "opening up" blues and rock n' roll to the white folk, what that really means is that because they were white, American Top40 radio was willing to hand to to the kids on a silver platter. But the kids who weren't willing to wait for butlers to hand them stuff on a silver platter had no problem finding the good stuff on their own.
How do you think the British Invasion started to begin with? It started because in fact what was called "race music" in the States was handed to the British kids on a silver platter via Armed Forces Radio during and after WWII. John Lennon and Keith Richards and Mick Fleetwood and John Mayall and Van Morrison and Pete Townsend and Eric Burton and Jimmy Page and Rod Stewart and all the rest of those guys grew up listening to the stuff our main (white) radio stations were in the meantime censoring and blacklisting.
It's not a question of stealing in this light, it's just that for those of us who were already ignoring the blacklists and digging into the *truly* underground catalogs, what the Beatles brought on to the scene was not all that new or amazing, but rather derivative; and in fact sounded a bit sanitized and uninspired compared to a lot of the stuff they were honoring and emulating.
I'm not saying you're wrong or right; what you like is what you like, and more power to you. I just ask that you remember that you are coming at this from the perspective of looking at a musical history book in which you can open any page you wish in any order, and that most white kids in 1962 that didn't bother digging for the real history of American music on their own were handed histories so censored that the Beatles and Elvis seemed to magically appear with their sound out of nowhere as if by divine creation like some musical big bang.
If you open you book to the Beatles first, yeah they will seem amazing. But when actually experiences things in fairly chronological order, the "magic aura" surrounding the Beatles does tend to disappear and get replaced by a bit of a "what's the big deal all about?" puzzlement.
Oh, I haven't even mentioned the "Stairway To heaven Effect"; yet, have I? Just wait until you've heard the entire Beatles catalog three hundred thousand times over, and let's see how amazing they sound

. When one has heard "Help" and "Hey Jude" an average of twice a day, every day of the year, every year for several decades, one tends to not crave hearing anything by or about the Beatles for a while, if ever again. This is also known as the "Clockwork Orange" effect
