A Lot has been written about what's in this particular 2 CD set re: versions , mixes , extras, omissions etc and how it all stacks up against the previously released Fillmore CD's .
I'm sure somewhere in the 77 reviews there is enough information to assemble a fairly accurate understanding . I'll try to set it straight in just one review.
About the previous releases :
A) The "Live at the Fillmore" CD is the same mixes / same tunes / same versions as the original LP released in 1971
B) How is "The Fillmore Deluxe" CD different than that ?
The "Fillmore Deluxe CD" contains All of the original Mixes and Versions taken from the Fillmore East Shows done in March 1971
(Except for One Way Out and Midnight Rider which were taken from their set at the final 6-27-71 closing of the Fillmore East show
And THAT whole set/ show ( 6-27-71) is now available as the 2nd CD in the"Deluxe Eat a Peach" CD release - with some minor omissions )
ALL of those "Fillmore Deluxe" mixes / versions were previously released on the following LP's:
"Live at the Fillmore": 1971, ( statesboro blues, done somebody wrong, stormy monday, you don't love me, hot lanta, elizabeth reed, whipping post)
"Eat a Peach" :1972 (trouble no more, one way out, mountain jam)
Duane Allman Anthology 1: 1972 (don't keep me wondering)
Duane Allman Anthology 2 : 1974 (midnight rider)
plus the unreleased 'Drunken Hearted Boy' w/ Elvin Bishop which closed the Fillmore run 3/71.
If you want something that feels and sounds like the original LP and has all of the extra tunes .... The "Deluxe" is the one .... THAT is as close as you are going to get with a CD.
C ) So How does this "Fillmore Concerts" CD different than those ?
1) You get a Different Mix :
a) drums and bass are more prominent
b) More upper mids in the guitar EQ ; Duane's Tone is more open and textured
( it's probably the best Tone he never actually got )
c) Dickie's Tone is more over driven ( probably a mic from another amp / cabinet mixed in)
and both guitars were probably altered to sit in the mix with the more prominent bass / drums.
d) more ambient room sound
2) Alternate Song Versions :
a) "Trouble No More" is looser than than the previously released live version
b) "Stormy Monday" includes the Harmonica solo that was omitted in the original LP / previous CD versions ( for good reason )
c) "Hot Lanta" : a pointless inclusion here with the novel sax. Saxes were used on the Friday night shows that rendered those performances unusable because they were out of tune.
d)" You Don't Love Me" has a looser edit / mix which includes Berry Oakley's bass at the first breakdown before Duanes first "Solo" spot.
Though Novel , they should have stuck with the previously released versions of those ... but with the alternate/ new mix..... THAT would have been a great sounding record.
3) Contrary to the liner notes :
"Elizabeth Reed" Is NOT some new performance / version.
"In Memory of Elizabeth Reed" is the Very SAME 'performance' as the original LP and all the various CD's to follow since its release in 1971.
As hard as that is to believe, Tom Dowd obviously forgot to go back and listen to the mix of the original LP and discover he had already done that splice / edit back in 1971.
Splicing the two different performances .... taking Duane's solo from the night before and splicing it on to the Sat night performance to 'create' the 'version' everyone has heard since its 1971 release.
4) Omissions :
a) The Midnight Rider : that appears on The Deluxe CD
b) the classic pre Whipping Post banter
a) Drunken Hearted Boy is also given the new mix ( though the song does appear on the Deluxe CD too )
b) One Way Out is the same version from 6-27-71 that 1st appeared on Eat a Peach and also on the Deluxe CD , BUT with the new mix / EQ
6) So Why get "The Fillmore Concerts" ?
For the guitar tones alone it really is the best one. I've got all 3 versions and the LP since 1972 but still, This mix is the best one for me.
( It's just not the Original Mix which some maybe so ' attached' to )
It's too bad about the inclusion of the inferior versions and edits , they should have stuck with the previously released performances but with the new mix for all.
It comes with a nice booklet though some of the pics are taken from 1972-3
If you are a real fan I would get it just to have it
If you are new to the ABB you may want to start with the other Fillmore CD's or even Eat a Peach to get an over all view of the band( studio and live , with and w/o Duane ).
If you like it, you may find yourself getting this one anyway.
Either way, Those Fillmore shows catch this band at some of its 'finest hours'.
7) These guys did a lot to transcend the Southern Rock label that ( unfairly and non descriptively ) came later.
They were visionary and artistic in their arrangements ( in that regard, these guys were closer to Weather Report ).
Their influences ran from jazz to indian to country to soul to gospel to blues and R&B.
With these recordings, they set a bar line that Nobody ( including themselves ) has matched since.
Just because some of these tunes may have lasted 10-20 minutes, they were in No way some 'Jam Band'.
They were in a whole other league, they were very compositional in the 'improv' sections of these tunes and THESE guys actually had something to say.
As Tom Dowd says in the liner notes 'it's his favorite fusion (of styles) album'.
