I have a question:
Given the enormous dynamic range of actual live performances, the sensitivity of speakers recording microphones, and limitations of actual amplification - wouldn't compression of some kind be a necessary evil?
Isn't it a trade off?

Today, recording technology can easily handle the dynamic range of uncompressed music. This hasn't been a problem for 50 years. Prior to that musicians made accommodation in their performance to the available technology. Playback technology can reproduce the full dynamic range of a symphony orchestra or other large musical ensemble, and the playback equipment need not be particularly costly unless the room is large (which probably implies an affluent consumer). A system with this capability need not cost more than a few thousand dollars. About the only technical reason for compression today is the desire for the music to be heard in specialized situations, e.g. as background music or in a noisy automobile. This is a pretty poor excuse for dumbing down music, especially since the technology exists today to inexpensively compress music during playback.
The reason for excessive compression is greed and ignorance. If one is marketing music to idiots who are unable to adjust a volume control then perhaps compression is appropriate. The present industry model for some musical genres assumes that the executives deciding on which music succeeds or fails commercially are idiots. But then most of the musicians playing in the hope of getting rich rather than out of love of music are probably idiots and their music probably deserves to be butchered.

I remember the old "Dyna flex" LP's ... awful, awful awful. MP3's sounded better. THink it has a similar root cause.
Agree that music loses something when compressed - but the "thwack" of a drum or some peaks are loud enough that I was wondering if a little compression would be "ok"

Do you mean "Dynagroove" which was a different process from Dyna Flex? I don't recall any Dyna Flex disks, but the Dynagrooves were horrible. Fortunately I only bought one with my own money.
It's OK to chop off one or two isolated peaks in a track if they are artifacts of multiple waves happening to roll in phase. (There are usually better ways of doing it than straight clipping.) If this is done with skill the result won't be audible and the rest of the track can be boosted. However, if the exact same processing is done repeatedly (e.g. on repeated drum hits) then the changes may be individually inaudible, but taking the track as a whole there will be degradation. It may manifest as a sense of unease or possibly as a conscious feeling that the recording is "unnatural".

That's another "depends" - who's the artist, what's the genre, what musical instruments, what's the mix of acoustic vs amplified, and so on.
A small acoustic vocal or instrumental group may be fine with no limiting or compression at all. Perhaps even a classical orchestra, depending on the work they're playing and who's in charge of the ultimate sound quality.
However, throw in a drum kit with close miking and you may need some limiting to keep the odd drum strike from overloading things. Move that to a rock group with the lead singer swallowing his mike with a bunch of amplified instruments getting banged, and you'll probably need a lot more compression and limiting to get the "sound" the producer is after.
I don't think many knowledgeable people on the recording side would claim that no compression and no limiting are the only way to record. The problem is that for some outfits, it's simply become a race to see who can make their music the loudest. Unfortunately with CDs, they have a brick wall when it comes to how loud you can make a recording. That means you have to clip severely and compress the daylights out of the music to win that prize.
I've never quite figured out who that impresses and why, but it's sure not the way I like my recordings.
