Long before the Davis estate had anything to do with it, for whatever reason, this was called "The Lost Quintet" with good reason. I'm sure there's a reason why Columbia didn't do something to document this band, but damned if I know what it is.
Just as the (re)discovery of the now-legendary "Second Great Quintet" precipitated the mainstreaming of a once "esoteric" musical sensibility, so might a reversal of the de facto supression of this band. The "walls" are finally starting to crack (and have been for the last 10 years or so, when those two grey-market CDs - Double Image & Paraphernailia - came out and all the underground talk of badassness from those who had actually heard the various tapes proved to be accurate, to put it mildly), but there's yet no (and may never be) a Plugged Nickel-like "Rosetta Stone" for this music. Part of that is because it was evolving so rapidly, but an equal part is that most of what exists is amateur recordings of variable quality. Again - where was Columbia?
People need to hear this band's output. At least people interested in jazz as something other than "repertory music" do, becuase this was a band where a lot of then-"controversial" currents in the music - free jazz, "rock" rhythms, and electric instruments - came together in a music that was still unmistakably "jazz". All the revisionary bullshit about how all those evolutions were "mistakes" and "not really jazz" and "commercial sellouts" falls apart when you hear this band play what it played how it played it.
There's a few bands whose lack of "official" documentation has really skewed the "common history" towards the inaccurate as well as allowing for the agenda-driven revisionists/faux-preservationists to get far more of a free pass than they deserve. From early in the 1960s, the Rollins-Cherry band is one, but at least they hade a little piece on RCA. From late in the 1960s, there's this, The Lost Quintet of Miles Davis. One - one - Japanese-only Sony CD, period. That and a buttload of bootlegs, audio and video.
No matter what you think about it, it's next to impossible to fully understand so much of what happened in the so much of the jazz of the early 1970s without hearing this band go from where it started to where it ended up. But how is that supposed to happen?
In the meantime, anybody who tells you that the '70s was when jazz "got away" from itself, please allow for the distinct possibility that they are either ignorant or else full of shit. There is that argument to be made, but making it to advance the cause of putting Humpty Dumpty back together again ignores the fact that one way or another, eggs end up getting broken, even if allowed to conclude their natural cycle.
Especially if allowed to conclude their natural cycle.
