I have both live sets(on 2 Japanese RM - RE) releases and I think the music is fantastic. Here is the personnel on the recordings.
Freddie Hubbard trumpet
Stanley Turrentine tenor sax
Herbie Hancock piano
Eric Gale guitar
Ron Carter bass
Eric De Johnette drums
You have already listed the personnel on Salt Song which is very extensive compered to the 6 man lineup on the live set.
Here are reviews I found for both the live album and Salt Song:
Live Album:
Scott Yanow of Allmusic stated "This LP pairs trumpeter Freddie Hubbard and tenor-saxophonist Stanley Turrentine, two very individual players who always brought out the best in each other. They stretch out on long versions of "Povo" and "Gibraltar" that clock in around 19 minutes apiece. The backup rhythm section (guitarist Eric Gale, keyboardist Herbie Hancock, bassist Ron Carter, and drummer Jack DeJohnette) is a major asset and inspires the two horns to play reasonably creative solos."
Syd Fablo of Rock Salted wrote "A really, really good — if strangely overlooked — live jazz fusion album, comparable to Cannonball Adderley‘s The Black Messiah and Donald Byrd‘s Ethiopian Knights, which is to say this is not formally or stylistically innovative but everybody involved delivers superb performances with a focus on warmth and heart. There also is an equally good Volume Two, on which Herbie Hancock shares top billing — strangely, because he plays on both volumes, but also not so strangely given the commonalities this music shares with his own Mwandishi group. As fusion was starting to drift into bland mediocrity, this is something else entirely, a vibrant, energetic and likable rock-inflected electric jazz performance that sidesteps the sort of pandering that usually goes hand-in-hand with fusion from this point onward. There are overt signs of structure, and efforts to make the performances sound proper and professional, but there is always a hint of something unruly and dangerous lurking behind every note. It is that sense of double meaning that makes this more than just a funky good time (which it also is)."[3]
Salt Song:
The Allmusic review by Steve Huey awarded the album 4 stars and states "it’s another fine, eclectic outing that falls squarely into the signature CTI fusion sound: smooth but not slick, accessible but not simplistic... All in all, Salt Song has dated well, partly because the arrangements don’t overemphasize electric piano, but mostly on the strength of Turrentine’s always-soulful playing".[2]
I agree with the two reviews of the live album, because owning it, I have listened to it to many times to count.
"Salt Song" gets 4 stars but I do not have that album so I cannot compliment on it. Suffice to say if Orpheus10 says its a good album I will listen to all of the songs on it via You Tube and decide for myself.
BTW, I am a big fan of Turrentine and own 24 of his recording sessions on CD including "Sugar" which I believe Creed Taylor (CTI) put together. "Sugar" is definitely a 5 star session, IMHO.
